My breasts started hurting last friday. I had sex with my boyfriend over two weeks ago, i am on the pill but we did not use a condom. My nipples do no hurt but the bottom and side of my boobs hurt a lot when apply pressure to them. I can jump up and down and they dont really hurt. I have pretty big boobs but they are swollen and seem to be bigger. Please help, am i pregnant, i cant be pregnant. Are these similar symptoms to pregnancy breast pain???
