When Can I Take A Pregnancy Test with hCG Shot?

Trace amounts of hCG can remain the body for as many as fourteen days after hCG injections. So it is best to wait before taking a pregnancy test.

What is An hCG shot?

hCG shots are sometimes known as “trigger shots”. They are injections that are given to women who need help triggering their ovulation or to help in lengthening the luteal phase of their cycles. Claim Your 20 Free Pregnancy Tests – Click Here

What are known “trigger shots”?

Pregnyl and Profasi are two brand names of these hCG trigger shots. These shots can be very helpful in many women for triggering ovulation or lengthening the luteal phase of the cycle, however you have to be careful taking a home pregnancy test shortly after having your trigger shots. Read on to find out why this is.

hCG and pregnancy tests

hCG is the “pregnancy hormone”, or the hormone that is produced in the body when a woman is pregnant. hCG begins to be produced right after the fertilized egg begins to implant in the uterus. hCG is released by the placenta. It is the hormone that is detected by a home pregnancy test. Therefore, if you take an hCG trigger shot too close to the time that you take a home pregnancy test, you might not get accurate results. You might end up getting a false positive because the pregnancy test thinks you are pregnant, but it is really just the leftover traces of hCG left from your hCG injection shot. This can lead many women to getting a false positive test, which is never a good thing for any woman who is trying to conceive.

So, how long?

Trace amounts of hCG can remain the body for as many as fourteen days after hCG injections. The rule of thumb that doctors use is that it takes one day for each 1000 units of hCG to leave your boy. So, if you get a 10,000 unit injection of hCG, it will take approximately ten days for it to all leave your system. Most doctors will err on the longer side of the time frame to ensure that you get an accurate result. So, in order to ensure that you get the most accurate result from a home pregnancy test, doctors recommend waiting a minimum of two weeks after taking hCG injections before testing. The longer you can wait, the better the chance that all of the remaining traces of hCG will be out of your body. I know that waiting can be hard, but taking a test and getting an inaccurate result can be even harder. Wait, if at all possible, to test.

Gynao went for hCG test and results were some 1 lakh. She is saying that it is obvious that no heartbeat minght come in USG and told me to wait for 2-3 more weeks. And is assuring that I am pregnant. Please provide your valuable feedback
