So according to my ovulation kits, I ovulated a week ago. And 3 days ago I tested my ovulation and it showed low fertility but me and my husband was in the mood so we had sex. But my period was supposed to start the next day I was even having spotting that night and my period is very regular. Now I’m 2 days late for my period but I know I can’t be pregnant because my ovulation showed low fertility the night we had sex, so I’m confused
