Calculate Your Fertile Window
To calculate your Fertile Window, you need to determine what day you ovulate.To do this, you need to know the length of your menstrual cycle . To calculate this you should note how many days have passed from the first day of bleeding in your last period, to the first day of bleeding in your next.From this figure, subtract 14 days from the end of your current cycle to determine the day you ovulate.If you have irregular menstrual cycles, or your cycle length varies from month to month, it will be difficult to calculate your ovulation date. Ovulation urine tests may be useful, and you should consider seeking further advice from your GP or a Fertility Specialist.
Frequently Asked Questions About Conception Dates And Conception Calculators
Is the date given accurate?
Its an estimate and gives a range based on your fertile period. The only way to know for a fact when you conceived is if you only had intercourse once between your cycles. The only way to know for sure is through ultrasound scan done after 8 weeks of pregnancy.
Can the conception date determine the father of my child?
It depends on when you were fertile and when you had intercourse. If you had intercourse with multiple partners during that time-frame, it could be either of them and the only way to accurately know is by a DNA test.
Why would I want to use a conception calculator?
As said in the above question, you might want to have a range as to when you actually conceived, especially if you were with multiple partners. You also might want to have an idea as to where you conceived to tell your children later on and embarrass them.

Example 33 Day Cycle Calculation Worked Back From Expected Date Of Period
If you started your last period on the 12th of August and because you have an expected cycle of 33 days, the period you missed should have started on the 14th of September. Taking 14 days off 14th of September would give you an ovulation date of roughly the 1st September. This gives you a fertile window of between 27th August and 2nd of September.

How To Spot The Signs Of Ovulation
Ovulation usually happens about 10 to 16 days before the start of your next period, so it helps to know your cycle length before you start trying to conceive.
You may never have considered when you might ovulate within your cycle, and if you have been using a hormone contraceptive such as the Pill, you wont have had a natural menstrual cycle for a while.
As a first step, mark on your ovulation calendar the dates that you bleed during a period. You can then count how many days from the first day of your period to your next period to work out the length of your cycle.
Best Time To Evaluate Cervical Length In Patient With Risk Factors
Some pregnancies are called high risk pregnancies because of some conditions that put the baby in risk of preterm birth. In cases where the mother is prone to have complications or experiences signs of preterm labour, an ultrasound is done to check the length of the cervix.
As your body gets ready for labour, the cervix softens and decreases in length. But if the cervix begins decrease before 37 weeks, there are chances of preterm labour and premature birth. Thus, cervical length is monitored in pregnant women, especially in those with history of premature birth, to reduce the risk and chart a plan to manage the pregnancy.
Our conception date calculator also provides you with optimal date when you should get your cervical length examined.

Example 28 Day Cycle Calculation
If the first day of your last period started on the 12th of August. This would mean your likely day of ovulation to be around the 26th of August. So, by adding 9 days to the 12th of August would give you a fertile date from the 18th of August through to the 27th of August. Any time you had sex during those 6 days could have resulted in you becoming pregnant.

Who Is The Father Of My Baby
If you have been with more than one man during your cycle, you may be wondering: “Who is the father of my baby?”
You can use your dates to try to figure it out, of course, but your best chance at knowing without a doubt who the father is would be to have a paternity test done once the baby is born.
If you would like to try to figure it out and you have regular cycles, here’s how:
Once you have your calendar marked, it’s time to analyze. Start with the first man. Were you with him any time leading up to ovulation or during ovulation? If so, he could be the father. Same thing with the second man, and so on.

How Many Days Before And After Ovulation Can You Get Pregnant
The sperm survives in the female reproductive tract for six days, and the egg is viable for 12 to 24 hours after ovulation. This means you can get pregnant from having sex six days before ovulation and one day after. However, for best results, Dr. Sinem Karipcin, an OB/GYN and infertility specialist, says, “The best days to conceive are the three days prior to ovulation and the actual day of ovulation.”
How Do I Calculate My Due Date
On average, a baby arrives 240 days after the first day of your last menstrual period. This is the gestational age, and it is what most doctors and health care professionals use to calculate the due date. It includes the two weeks prior to conception when a woman is not pregnant. Of course, this is based on a 28-day cycle, and days will need to be adjusted for longer or shorter cycles. But, even with adjustments, less than 10 percent of women actually deliver on their calculated due dates, so giving birth two weeks before or after the estimated due date is normal.

How Long Should I Try For Before Seeking Specialist Advice
Conception is a complicated sequence of events because all of the following need to be in place for it to occur:
- Regular egg production by the ovaries
- Healthy sperm, with the ability to move and the correct shape
- Unblocked and healthy fallopian tubes and uterus
The number one factor affecting a couples chances of conceiving is the womans age. The number of healthy eggs a womans ovaries contain will dramatically decline with age and especially for women over 35. Most people start to consider seeking professional advice after six months of trying to conceive naturally without success. This is even more important if youre over 35.
What Is The Difference Between Ovulation And Fertile Days
‘Ovulation’ is the process of an egg being released from an ovary and this happens 12-16 days before her next period starts.
‘Fertile days’ are the days during a woman’s menstrual cycle, leading up to and including the day of ovulation, when she has the ability to become pregnant if she has unprotected sex.
When are the highest and lowest chances of getting pregnant?
The most fertile days each cycle when you have the best chance of getting pregnant from unprotected sex, are the day of ovulation and the day before these are the 2 days of peak fertility. However, due to the fact that in a woman’s body during her fertile time there are also a few days before this when you also have an opportunity to get pregnant these are the days of high fertility. Outside this fertility window of about 6 days, the chances of getting pregnant are low.

Improve Your Chances Of Getting Pregnant
If you want to improve your chances of getting pregnant, you need to answer one simple question: “When do I ovulate and when are my fertile days?” Knowing exactly if and when you ovulate is the single most important information you need to know when trying to get pregnant . You can only get pregnant from having sex on your fertile days, which are the 4-5 days before and the day of ovulation. If you know when you ovulate, you can also time sex better.
What Happens During Ovulation
Every month, one of your ovaries has immature eggs that begin to develop in what are called follicles. Usually one of these follicles will begin to mature and the others will stop growing and eventually degenerate. Eventually, the follicle matures and releases the egg from the ovary. This is ovulation and it typically occurs approximately two weeks prior to your menstrual period. For about twenty-four hours after ovulation, the egg can be fertilized.
Finding out when and if you ovulate is one of the most important factors when trying to get pregnant.If you don’t ovulate, you can’t get pregnant.

How Is The Conception Date Calculated
Conception, the fertilization of the egg by the sperm usually happens 266 days before the due date and the due date is calculated 266 days after ovulation conception and fertilization. The last menstrual period usually happens about 14 days before ovulation, so the due date is calculated 280 days after the first day of the last menstrual period.
Can My Due Date Change
Yes, your due date can change. While its definitely not a reason to worry, your doctor may change your due date for a number of reasons as your pregnancy progresses.
It may be that you have irregular periods and your early ultrasound dating was off, or that your first ultrasound was in the second trimester.
It could also be because your fundal height is abnormal, or your levels of alpha-fetoprotein , a protein made by the baby, are outside the usual range. Talk to your practitioner if you have any questions or concerns.

Using Ovulation Test Kits
Ovulation predictor kits are available from chemists and are fairly simple to use. They work by detecting a hormone in your urine that increases when ovulation is about to take place.
The simplest ovulation test kits check for luteinising hormone , which surges 24-36 hours before ovulation. This will help to identify the best two days for conception, although a woman can be fertile for a day or so before and after this time.
It is best to become familiar with your usual menstrual cycle to help figure out when you should start testing. If you have an irregular cycle then an ovulation predictor kit can help you identify the time of ovulation, but expect to use more of the test strips.
Can The Pregnancy Conception Calculator Be Wrong
Yes, of course. So, when does conception happen? There is no possibility being 100 % sure about it. You may be a little bit more certain if you track your cycle and have it perfectly regular. But even ultrasounds and blood tests aren’t faultless. Remember, that your fertile window begins up to 5 days before ovulation and ends one day after it. So, although your conception date is, e.g., 11 July 2019, the intercourse that caused the pregnancy may have occurred as early as 6 July. However, with our conception calendar calculator, you can make an estimated guess!

How To Figure Out The Conception Date
Let’s say you ovulate on day 10 of your cycle. The egg comes out of the ovaries and waits for 24 hours in your fallopian tube. There’s two possibilities of what could occur:
If you have intercourse during day 7 of your cycle and you ovulate on day 10, it’s possible that conception can begin on day 10 or 11, depending on how quickly the sperm finds the egg. If you have intercourse on day 10 or your cycle, the same day you ovulate, conception can begin that day or the 11th day.
Making The Fertility Window Work For You
With a pattern of regular lovemaking achieved, the next thing to do is identify that handful of days directly prior to, and including the day of ovulation. Identifying this “window” will significantly boost your chances of conception.
The above conception calculator can help with the process of tracking your personal biological cycle, and thereby assist you in determining your fertility window. To use the calculator, note the first day of your last period. Then note the length of the cycle until your next period. Finally, input the numbers into the calculator and get an estimate of the best days for intercourse and conception.
You can help the process along by keeping a basal body temperature chart. Tracking your basal body temperature and your cervical mucus can help you get pregnant. The patterns you see month after month can help you predict ovulation, and once you know when you’re likely to ovulate, you can have sex at the best time for conceiving.
Your basal body temperature is the lowest body temperature in a 24-hour period. To get an accurate reading, you must take your temperature when you first wake up in the morning, before you even sit up in bed. And you’ll need to use a basal thermometer which is sensitive enough to measure minute changes in body temperature. Try to wake up and take a reading at about the same time each morning.
