Sore breasts

Pia • Miscarriage with my 4th, trying to conceive baby number 5. Finally pregnant with my 5th 🌈
I'm been trying to conceive #2 for about a year. I'm on my 3rd cycle of clomid. Right now I'm in the middle of my fertile time and my nipples are really sore. This usual doesn't happen until AF is about to start. Has this happened to anyone else???
