A bit confused

Danielle
I stopped bc pill feb. Had withdrawel bleed. Ovulated 3 weeks later and real period 2 weeks exact from ovulation.  Going by glow im due tomorow but i didnt get positive opk unless i missed the window. I have bd so thats not problem i just feel i cant predict if my period will come as i couldnt catch ovation for sure. Time will tell tomorow
