I get to start my progesterone suppositories this week and as much as I'm excited- I am very nervous..

I always use OPKs, probably every other day from CD 12-22 to get a general idea of when ill ovulate, and I usually throw them out after.

Whereas our doctor has asked us to keep them this cycle, and really knuckle down on tracking. (This is to make sure I take my progesterone on time so we have the highest chances of conception.)

Well I'm now on CD 18 and am not sure if I ovulated yesterday..

I used opks and it looked pretty dark in the AM. Not quite as dark as the control line, but mine never get that dark and I always ovulate confirmed with BW. Anyways this one was clearly much darker than the one I took the day prior-because of that I decided to take another one in the PM, but when I did, it was almost stark negative.

Me and hubby bd with preseed anyways, but almost right after, I got a bloated crampy feeling, which is usually my indication ovulation is coming.

I assumed I was ovulating and went to bed, but now today I am super paranoid because I usually ovulate around CD 19-21, and yesterday was only CD 17.

I just really don't want to start my progesterone too early and throw off my chances of conceiving. Or too late and have gotten to the implanted baby too late. (I have a history of chemicals.)

I've read that you can have one slightly smaller surge before your main one, and there's not much way to tell the difference other than a negative opk for a few days in a row, but I can't take that chance and not use my progesterone if I already did ovualte.

I'm so confused and just not sure if I should trust my gut saying I already ovulated or I should trust glow saying I ovulate on the 10th (Wednesday).

Thoughts or Advice ?
