How Does Conception Work With Ivf
Conception still works the same way sperm must fertilize an egg. However, with in vitro fertilization , sperm fertilizes an egg in a lab. An egg, either from the intended parent or a donor, is mixed with sperm from a parent or donor. Conception happens when sperm fertilizes the egg.
Once conception occurs, your provider places the created embryo inside the uterus that will carry the pregnancy for implantation.
Blood Pregnancy Tests Used By Doctors
Your doctor can give you a blood pregnancy test as early as 1114 days after ovulation. To perform a blood pregnancy test, the doctor draws blood from a vein in your arm. This blood is sent to a laboratory for testing. The results of most blood pregnancy tests take at least a couple of days. The laboratory then advises the doctor of the result.Blood test results are about 99 per cent accurate and can detect lower amounts of hCG than urine pregnancy tests. The 2 main types of blood pregnancy test include:
- Quantitative blood test measures the exact amount of hCG in the blood and can give you an estimate of how far along the pregnancy has progressed.
- Qualitative blood test only checks for the presence of hCG. Since this test doesnt measure the exact levels of hCG, it cant offer an estimate of gestation.

Second Trimester Anatomy Scan
A second trimester anatomy scan is a detailed ultrasound that helps a doctor or ultrasound technician see fetuss organs, the location of the placenta, and determine the health of the developing baby and the pregnancy.
Healthcare providers usually schedule it within weeks 1822 of the pregnancy.
At this time, the developing baby is usually large enough for the healthcare professional to see the genitals. A skilled technician can often identify the sex based on their appearance.
A 2012 study of two-dimensional ultrasounds found that technicians were slightly better at predicting male fetuses than female, with a 100% success rate for males compared with 97.9% for females.
A healthcare provider cannot always detect the sex with an ultrasound because the developing baby may be too small. Their position might not be ideal for viewing the genitals, or something might obstruct the technicians view of the genitals.
When this happens, a healthcare professional might recommend coming back for another scan in a few weeks.

How Does Conception Occur
Conception is when sperm and an egg join together. Its one of the many steps that happen to create a pregnancy.
Conception is closely related to a persons menstrual cycle. A menstrual cycle describes the sequence of events that occur within your body as it prepares for the possibility of pregnancy each month. Women or people assigned female at birth ovulate during their menstrual cycle. Ovulation is when your ovary releases an egg for fertilization. Tiny finger-like structures called fimbriae help guide the egg through your fallopian tubes towards your uterus. During this journey through your fallopian tubes, an egg can be fertilized by sperm.
If a sperm is successful on its quest to fertilize an egg, the now fertilized egg continues to move down your fallopian tube, dividing into two cells, then four cells, then more cells. About a week after the sperm has fertilized the egg, the zygote has traveled to your uterus. It’s now a growing cluster of about 100 cells called a blastocyst.
The blastocyst then attaches itself to the lining of your uterus . This attachment process is called implantation. However, just because conception occurs doesn’t mean implantation will. Sometimes implantation doesn’t happen, and you pass the fertilized egg in your next menstrual period.

The process of getting pregnant in a 28-day menstrual cycle is:

If You Know When Your Next Period Is Due
If youve been tracking your period *and* have a regular period, its going to be easier for you to pick the best time to take a pregnancy test.
To understand why that is, you need to understand a little more about how pregnancy tests work. Ready?
Pregnancy tests measure a hormone known as human chorionic gonadotropin , which is colloquially known as the pregnancy hormone, explains , MD, an OB-GYN at Yale University.
Heres the thing: While the amount of the hormone the tests can detect varies depending on whether its a urine or blood test, typically your body doesnt produce enough of this hormone to be detectable until at least 10 days after the sperm has successfully implanted the egg.
And the sperm does *not* implant the egg immediately.
It takes some time for the egg and sperm to travel together down the fallopian tubes, where they first meet, down to the uterus where it implants, Minkin explains.
Once the fertilized egg implants in the wall of the uterus, it starts dividing. It isnt until the fertilized egg starts dividing when it starts to develop the placenta, which is where the pregnancy hormone is, she says.
All in all, it usually takes about 9 days after conception for the body to create the 20 to 25 milliInternational units per millimeter of HCG that most urine tests need in order to trigger a positive result.
Blood tests can measure the exact amount of pregnancy hormone in your blood, and they may be able to tell you your pregnancy status sooner. For example:
Your First Three Weeks Of Pregnancy
Hereâs the thing: Because of the way pregnancy is usually measured, youâre not actually pregnant during the first two weeks or so of your pregnancy. Healthcare providers calculate the length of an average pregnancy as 40 weeks, starting from the first day of your last menstrual periodâthis is known as the LMP dating method. So, when youâre 1 week pregnant, youâve only just started your period. At two weeks pregnant, youâre ovulating. And since ovulation happens about 14 days after the start of your period you canât really become pregnant until week 3 at the earliest.It can be mind-bogglingâwe get it. But, for the sake of calculation, and what you and your healthcare provider will consider as 1 and 2 weeks pregnant, youâre not actually pregnant! But although at 1, 2, or 3 weeks pregnant you may not notice any of those very early signs of pregnancy, there may be a lot happening on the inside.

The Best Time In Your Cycle To Take A Pregnancy Test
The best time to take a pregnancy test is after your period is late. This will help you avoid false negatives. If you’re not already keeping a fertility calendar, proper pregnancy test timing is a good reason to start one.
If your cycles are irregular or you dont chart your cycles, do not take a test until you have passed the longest menstrual cycle you usually have. For example, if your cycles range from 30 to 36 days, the best time to take a test would be day 37 or later.
Something else to consider is whether you know if your period is even late. According to the FDA, out of every 100 people, between 10 and 20 will not get a positive pregnancy test result on the day they think is just after their missed period, even if they are pregnant.

You can ask them about prenatal care options or specialists who can help guide you through your pregnancy. Ask your doctor about any changes you need to make to your lifestyle, medications, or diet to keep yourself and your baby healthy for the next nine months.
If your test results are positive but you didnt plan to get pregnant, ask your doctor about available options, including:
- carrying the pregnancy to term for adoption
- what to do if you want to continue your pregnancy
You can also receive help from a clinic or health center that specializes in reproductive health and child care, like Planned Parenthood.
