250mcg is approximately 6700IU. Ovidrel has a half life of 27 hours, meaning the amount in your system drops by half every 27 hours (this can be a bit faster or slower depending on your metabolism). So, the day after the shot, you'd have about 3,350IU in your system, the day after that about 1,675, etc. Assuming that less than 10IU or so is safe not to give you a false positive pregnancy test, the average time would be about 11 days.

Good luck!!

Your trigger was just 250? Mine was 5000 and took about 8 days to go completely negative. 10,000 can take about 12. If yours was just 250, it should be gone in a matter of days. Anything past your implantation stage - 6-12DPO should be legit.

essemkay, that conversion makes more sense. Didn't know there were two units of measurement. So yes, 6700 will take roughly 9-11 days or so, so you will either want to test to get a baseline and see if it gets darker if testing from 8DPO and on or just wait until 14DPO when it should be out for sure.

Test it out starting around day 8 and you'll know for sure.

Just to update, looks like you did 5k units as well (not 6700 - thought that was an odd amount) if you follow this thread:

I did forget when I did IVF I took a few rounds of Pregnyl after the transfer. It's supposed to help with the implantation. Will have to ask my Dr. about maybe doing it next month.

socigirl, that thread you linked is wrong. Ovidrel 250mcg is about 6700IU and the half life is 27 hours.

My wife took the ovidrel trigger shot. 14 days later her home test said pregnant. Later the blood work confirmed that she was pregnant. The nurse said the 250 mcg ovidrel stays in the system for 10 days. Goodluck.
