Question for Ghost

[Hopeful Heather]

I had hcg trigger on July 29 of 15,000 iu , 5 day transfer of 2 blasts on 8/5, Im to have my first beta on 8/14. Would the hcg trigger still be in my system today that would cause a postive on a hpt?

HCG leaves the system at about 1,000cc a day. So if you had it on July 29, 15 days ago, it should be out of the system by now.

It takes 10-12 days for the trigger to clear. Because of the exponential decline in hCG level (falling by about half every 36 hours), you have had about 10 half-lives by now, and your levels from the trigger should be undetectable (less than 1 IU/l in your blood).

The time to decline to nil actually does not depend all that much on how much you take. Because of the exponential decline, a 15,000 IU dose stays in your system only a little longer, maybe about one more day, than would a 10,000 IU dose.

Short answer: The trigger should not be able to cause a false positive at this point.

At 7 days post day 5 transfer, you are starting to have a decent chance of seeing it on an HPT. A viable pregnancy would typically have hCG over 50 by now.

Best of luck.

Thanks so much for your replies! I took a clear blue easy early detect hpt this morning and it came up positive but then I was reading about the hcg trigger and thought it could have been a false positive due to that.
