4 days late. I’m sick of the waiting. I have thick white cervical mucus. Cramping. Irritable. I feel like I’m about to start but haven’t. I came off BC in September and have been regular every month besides December and now this month. In December I was 12 days late. However, this month we didn’t use protection at all.. but I also don’t track ovulation. I took a test the Saturday before my period was due but it was negative. Not sure why my period is late..., any advice?
