Not yet. I might asks for an ultrasound though. I found this website that explains all of the reasons for mid-cycle spotting. It can happen with people who didn't achieve ovulation because of an estrogen withdrawal. Or for people with ovarian cysts, which I've never been checked for, it can happen when a cyst bursts. Also, because I usually have multiple fertile cm surges throughout my cycle, that can indicate my body trying to ovulate multiple times before it actually succeeds and then the temp shift confirms it. I've had lots of sharp cramps the last few days, in both ovaries but mostly my right, and also intestinal cramps. I talked with my husband at length about it today and he's just as baffled as me. My temp this morning was slightly higher, but I also took it later than usual. We figured we'd wait until next weekend to see if AF comes because that would be a few days longer than my last cycle.
Thank you guys for your support and for listening. DH imagines the distant future will have instant scans and tests so we'll know exactly what's going on in there. But alas that stuff only exists in sci fi movies :/.
