Bbt/opk chart

Katryce

I need an opinion! Ive been using ovusense which takes incredibly accurate BBT readings. My chart was indicating ovulation the last coulple days. I got my confirmation this morning. BUT ALLLL of my OPKS have been negative?? Ive been taking them twice a day too. No CM etc. Really bummed because i wanted to give a good try and fear i may have missed the window. Only Bd'd yesterday, and that is logged ovulation day. Has this happened to you?
