How To Know What Day You Got Pregnant

Determining If Labor Is Premature

When Did I Get Pregnant? How to Figure Out When You Got Pregnant or Conceived

Babies who are born too early are at risk for numerous health problems. There are steps we can take to slow or halt preterm labor. With that said, there are also risks to the medications used to stop preterm labor, both to the mother and the baby.

You and your doctor have to decide together when the risks of allowing labor to continue to outweigh the risks of intervention. This is partially determined by knowing which week of pregnancy you are in.

There are also risks to the baby and mother if a pregnancy goes on for too long. Post-term pregnancy is when birth does not occur by week 42 . If this happens, your midwife or doctor may decide to induce labor.

When Did I Conceive Or Get Pregnant

The best way to calculate the day you likely conceived is to figure out approximately when you ovulated. According to Dr. Jennifer Landa, a board-certified OB/GYN, “If you have a “perfect” 28-day cycle, then ovulation happens on day 14 and you can get pregnant for about 12-24 hours after ovulation. Of course, many women don’t have a 28-day cycle. Anything from 21 days to 35 days is considered normal. So to figure out when you got pregnant if you have a different cycle, ovulation comes 10 to 14 days before your period.” If you had sex during this fertile window, then it is possible that you conceived during those days.

What Is Naegele’s Rule

  • Move the date back three months
  • For example, if the first day of your last period was August 11, 2022 you would:

    • Move the date back 3 months
    • Your due date would be May 18, 2023.

    If your fertility app gives you a different date than the one calculated by your doctor, it most likely is because it was based on the ovulation date and not the date of your last period. If you ovulated earlier or later than day 14 of your cycle, this would shift your due date accordingly.

    How To Use A Conception Calculator

    You dont have to do much for using a conception calculator. All you have to do it type the length of the menstrual cycle and the first day of last period. When you will input this information, the calculator will generate the answer. If you want to calculate your gestational age, then add two weeks to the answer.

    Special cases of having longer or shower cycles require extra steps. But that is why you calculate the date manually. Once you use an online conception calculator, it wont matter.

    A due date calculator may not be completely accurate. This is especially true if you arent exactly sure when you had your last period, you have irregular periods or you dont know when you conceived.

    If I Have A Negative Pregnancy Test After I Have Missed My Period Does That Mean I Am Not Pregnant

    A negative result can mean that you are not pregnant, you took the test too early, or you took the test wrong. Pregnancy tests vary in their sensitivity , and you may not have given your body enough time to produce enough hCG hormones that will show up on the test.

    Also, if you let a test sit for too long , the test is invalid. It is best to follow the instructions and wait until you have missed a period before taking the test. Some women show up accurately on a test the day they miss a period, while others may not show up positive until 3-4 weeks after a missed period.

    We encourage women to test after a missed period if the result is negative they should wait a week and test again if a normal period has not started.

They are termed chemical pregnancies. If you have been trying for a long time to become pregnant, it may be especially beneficial for your mental health to wait for a more reliable test result.

    What If I Have Irregular Periods Or Long Cycles

    Some women have cycles that are consistently longer than the average 28-day cycle. In these cases, a pregnancy wheel can still be used, but some simple calculations are necessary.

    The second half of a womans menstrual cycle always lasts for 14 days. This is the time from ovulation to the next menstrual period. If your cycle is 35 days long, for example, then you probably ovulated on day 21.

    Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.

    For example, if your menstrual cycle is usually 35 days long and the first day of your LMP was November 1:

  • Subtract 14 days to find your adjusted LMP date .
  • After you calculate your adjusted LMP date, simply mark it on the pregnancy wheel and then look at the date where the line crosses. That is your estimated due date.

    Some pregnancy wheels may allow you to enter the date of conception which occurs within 72 hours of ovulation instead of the date of your LMP.

    Look At The Following Scenarios And See If Any Apply To You

    Scenario 1: You were with Guy #1 on June 20th. You got your period around June 28th. You then were with Guy #2 from July 1st-3rd and July 11th-13th.

    Who is the father? Guy #2 would be the father since you had a period after Guy #1. Also, you were with Guy #2 during your fertile time.

    Scenario 2: You have your period on June 28th. You were with Guy #1 on June 29th, July 3rd, and July 5th. You were with Guy #2 on July 7th-11th.

    Who is the father? Guy #2 is most likely the father since you were with him closest to your fertile time. If for some reason, however, you ovulated sooner than the 10th of July, there’s potential that Guy #2 could be the father since his sperm may have lived from the 5th-10th. In this case, I suggest a paternity test so there aren’t any doubts.

    Scenario 3: You have your period on June 28th. You were with Guy # 1 on the 10th of July, and you were with Guy #2 on the 12th of July.

    Who is the father? There’s no way to know without a paternity test. Since you were with both men so close together, it’s possible that both of their sperm was in you when you ovulated and either one could be the father.

    Again, a paternity test would be the sure way of knowing who the father of your baby could be. Once the baby is born, the test can be done and no one will have second guesses.

    A woman who wants to have a baby should monitor the intervals between her periodsin other words, whether the first day of her period tends to occur the same number of days apart every month, which is considered regular. Conversely, her periods may be irregular, meaning her cycle lengths vary from month to month. By tracking this information on a calendar, a woman can better predict when she might be ovulating , according to research published in The New England Journal of Medicine . This is the time every month when her ovaries will release an egg. There are also some apps that can help with the tracking, such as GlowOvulation period tracker .

    Working Out Your Due Date

    1-minute read

    Once you have confirmed that you are pregnant, you will want to find out when your baby is due to arrive. The average pregnancy is calculated at 282 days from the first day of your last menstrual period.

    However babies rarely keep to an exact timetable, so a full-term pregnancy can be anywhere between 37 and 42 weeks. A baby born before 37 weeks is considered to be premature and anything past 42 weeks is considered overdue.

    Due dates are usually calculated on your last period instead of the date of conception because of a number of reasons.

    • Although the average woman ovulates approximately 2 weeks after her period, the exact time is not always known.
    • Once an egg has been released, it can remain fertile for up to 24 hours.
    • Sperm can last for up to 5 days after intercourse to fertilise an egg.

    If your periods are irregular or you are unsure of the date, an ultrasound will help determine the development of the embryo and your due date. Ultrasound scans can be done at any stage of pregnancy after the first 6 weeks. The best timing for an ultrasound to determine the due date is between 8 weeks and 13 weeks 6 days.

    You can use the Pregnancy, Birth and Baby due date calculator to work out when your baby is due.

    Some doctors will refer to your due date as ‘expected date of confinement’ or EDC.

    For a variety of reasons, a lot of women dont know when their last period was . A history of irregular periods, medications and plain ol forgetting are all normal reasons to be unsure.

    A transvaginal ultrasound can help to figure out your estimated due date, especially when done in the first trimester. The ultrasound technician will measure the size of the embryo and use the information gathered to determine your due date.

    Surprisingly, as your pregnancy progresses, it becomes harder to calculate the gestational age and size of the fetus with an ultrasound .

    Contact Your Obgyn As Soon As You Think You Are Pregnant

    Call your OBGYN clinic as soon as you find out youre pregnant. When you call in, your provider will review your medical history to determine the timing of your first prenatal visit. If you are a woman with no medical problems and under the age of 35, your first prenatal appointment will likely be 3-4 weeks after your missed period.

    Some women should be seen sooner than others. For instance, if a woman has a history of ectopic pregnancy , she should be seen within a couple of days. Certain other medical conditions warrant an immediate visit with the provider.

    Note: Ectopic pregnancy is when a fertilized egg grows outside of the uterus, such as in the fallopian tube. The earliest symptom of ectopic pregnancy is typically light vaginal bleeding soon after a positive pregnancy test. If this happens, call your OBGYN to schedule an ultrasound right away. The ultrasound will identify if the fertilized egg is growing in the uterus or if it has attached somewhere else.

    An ectopic pregnancy cannot be moved to the uterus and requires treatment such as medication or surgery. If the ectopic pregnancy continues growing to 5 or 5.5 weeks after conception, it could cause more serious complications, such as a ruptured fallopian tube, which can result in life-threatening internal bleeding. Symptoms of a ruptured fallopian tube include sudden and severe pain, abnormal bleeding, lightheadedness, and shoulder pain.

    When Should I Call My Doctor About A New Pregnancy

    If youve missed your period and gotten a positive pregnancy test, your next step will be to call your healthcare provider for your first appointment. While scheduling, your provider may ask if you have already started taking a prenatal vitamin containing folic acid. Prenatal vitamins are important in early pregnancy because they help in the development of your babys neural tube. The neural tube will become your babys brain and spine. Many healthcare providers recommend that anyone who could become pregnant take folic acid at all times.

    If youre planning a pregnancy, a preconception appointment with your healthcare provider is a good place to start. A preconception appointment is especially important if you take medication for a chronic illness or have other medical conditions like diabetes, high blood pressure or lupus.

    During this appointment, your provider will discuss any current medical conditions, as well as your general health before pregnancy. This appointment is meant to get you into the best place for a new pregnancy.

    However, these data that we have given previously are only useful in cases in which the woman has a very regular period. As a general rule, it is totally impossible to know the exact moment in which the pregnancy occurred. Through a transvaginal ultrasound, the gynecologist can get very close, but even so, the pregnancy dates can end up dancing for days or even weeks. And it is that they, when talking about the date of fertilization, are based mainly on the size of the baby , and that is why it is not exact. One ultrasound may mark one day, and then another may mark a totally different day.

    Unless the woman is on hormonal treatment , it is very difficult for her to know in which relationship the fertilization took place. To know the exact moment in which the pregnancy occurred, it is necessary to keep an established calendar of the days in which sexual intercourse is had, as well as to combine these data with the ovulation moments and the days in which the woman it is more fertile . Only in this way can you know the exact day and, even with this care, you could end up failing, since if you have relationships two days in a row, the fertilization date could end up doubting between one or the other.
