I have gotten my period on progesterone and I've not gotten it, so it's tough to make that call. I agree with 21:37, take an HPT. I got a faint positive 7 days past a 5 day transfer. You're about in that window, because that would be 12 days past retrieval, right now you're at that as of tomorrow a.m.

I will say the times I got my period I felt the same "period is coming cramps" that I did when I wasn't pregnant, so don't go by that. You're on all these meds, so everything is engineered now. Symptoms mean nothing.

If you're inclined (and won't freak out over an early negative), I would take a HPT. I had a very, very (barely there) faint line at 6dp5dt and am now just over 5 weeks (still being cautiously optimistic until the first U/S next week). I used a wondfo test, which I believe are ultra-sensitive (20 mlU, I think). Note though, that if you didn't test until your trigger was out of your system, you can't be sure that a faint positive is a pregnancy and not just residual hCG.

You won't get your period if you're still taking progesterone (which sucks, I know). Hang in there.

Hello
I am probably way over thinking the "cramps" and I am convinced I am having now. I did ET on April 22 and ovulation/retrieval on April 19. I have always had a very regular 28 day cycle. I am curious though if I am NOT pregnant, should I expect that my period will start on Thursday or Friday this week, about 14 days post ovulation? I am still on daily progesterone so will that affect my period starting? Im actually too scared to take a pregnancy test, I just can't take another negative test. I would almost rather just wait for my period to start.
My dr says it still way too early to test but I am going on 12 days Post ovuatlion and 10dp3dt and that seems like plenty of time to know one way or the other.
