I have already stated about the breast tenderness,swelling,but not always theres like a tingling sensation. My nipples hurt really bad when they get really hard out of the blue (which kinda when you get arouse kinda hard) and even when I don't touch them there really sore. Well the right one is more sore then the left sometimes. The 17-21 was during my ovulation time my boyfriend and I had sex from the 18-22 but of course he used the pull out method each time(which yes I know can cause pregancy as well).The 23 when I woke up my breasts started hurting badly and I at least have to use the bathroom now 3-4 times during the night which I normally never have to do when I'm sleeping. Any help at all would be helpful.
