Pregnancy symptoms?

Lily • Breast cancer survivor, saving before TTC.
So at first I thought it was weird how. Much my breasts hurt when normally I don't get breast pain. If I do, it definitely disappears a few days before my af comes. Today it is supposed to come! Nothing yet, still breast pain and I've gained a little weight. Still within my normal range, but normally I drop a few pounds before af and get (tmi) diarrhea, this time a little constipated. I would be so happy if pregnant! Hopefully af doesn't come around today.... Wish me luck!
