It usually takes at least 6-8 days for the trigger to get out of your system, I have found that if I drink a little extra water it gets out faster. Feel free to test every day, but to avoid the stress and save money I usually start testing to make sure it is all out of my system on the eighth day past the trigger. Sorry, I dont know much about suppositories, I take oral progesterone. Good Luck!!!
They say 1 day for every 1,000 units. So if you did 10,000 units, you could get an accurate hpt after 10 days. Everyone is different though. It may be out sooner or later, depending on how your body metabolizes it. You can do a hpt everyday, just to see the test line get lighter. That way if it starts getting darker, or completely neg then a couple days later it's positive then you will know it's a true positive. On your progesterone question, I do one in the morning when i wake up and one before i go to bed. That is what my RE told me to do, so i would suggest to do that. And trust me, we all COMPLETELY understand about wanting a perfect cycle!
