I took an OPK yesterday morning and it was negative although the line was nearing positive (I could tell that it would be probably next day). I had loads of EWCM. This morning I take an OPK and it’s positive. I don’t see any EWCM like I was before but dismiss that. Then mid-day I notice white lotiony cm which is normally my indication ovulation has passed. I take another OPK this afternoon and it’s negative/fading from my positive. I take another OPK an hour or so later to see and it’s negative too and even more white thick cm. Would you say I caught the very end of my LH surge and now ovulation has passed? Seems like a short window. We did have sex 2 days ago.
