no bbt rise...

Adie

So I've been ttc for about a year now. I tracked bbt for a few months and stopped because I never felt like I could see any sort of pattern and it felt like a waste of time. I use opks regularly and always get my positive right on time. Recently went to a fertility specialist and had all the tests done. They couldn't find anything wrong, my ovaries look fabulous, etc, etc... so basically, I'm ovulating. BUT.. in an attempt to do EVERYTHING right one last month before starting treatment, I'm tracking bbt again this month. I ovulated a few days ago and my temps have been pretty consistent with no rise at all. So what's the deal?? Any bbt veterans have any insight?

Thanks ❤
