So you have done your IVF, and you are now in the most difficult part, the two week wait before you are supposed to be tested.
So why the two week wait? Must you wait for two weeks?
That depends if you are doing a frozen embryo transfer or a fresh embryo transfer.
If you did a fresh transfer, you probably have taken something called the trigger shots. That means you may still have lingering HCG in your blood. When you do a blood test, you are actually testing for the HCG in your blood. So if you have HCG from the trigger shot, that may mean your test is a false positive and may caused you a lot of heartache.
If you did a frozen transfer, you probably did not take something called the “trigger shots”. That means if there should be no HCG lingering in your blood UNLESS you are pregnant. So for frozen transfer, the date you can test is actually earlier.
So what is HCG and why pregnancy test for HCG?
Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually forms the placenta after implantation.
Once implantation starts, the blastocyst starts producing HCG. So if you have a 3 days implant, needs another 2 days to become a blastocyst before it can implant.
So Day 5 frozen implant and then 10 days later, you get implantation and you get HCG in your blood. So you don’t need to wait 14 days, but that’s the safest.
However if it is a fresh 5 day transfer is a different because of the trigger shots.
