I'm on the pill but this week was my fertile week according to the app and I know it's not accurate if your on the pill bc you don't ovulate. But....like 3-4days before my supposed ovulation day I started having sore nipples. I NEVER have sore nipples ever! It is now almost a week since the sore nipples happend and the soreness has gradually gone away with my left one still slightly sore to the touch. Maybe I did ovulate? Or maybe I became pregnant? I can't remember if I've taken any pills late recently. I just found it odd that I all of a sudden had sore nipples when it's never happened before.
