Sore nipples

Jenny

So I just pass my ovulation. The last 2 days now my nipples been so sore to the touch. I know it's way to early for pregnancy. But why is my nipples so sore? I was supposed to get a pelvic ultrasound done tomorrow but I had to cancel it. Turns out my insurance only covers part of it. It would of been alot out of pocket. So my question is has anyone else have really sore nipples?
