My girlfriend has been having very sharp pain in her vaginal-stomach area after sex, we wonder if she's pregnant or not because a few weeks ago she had very sensitive breasts. Her right breast was swollen and hurt to touch, even her nipple with some white discharge. The doctor said it was a swollen or clogged duct. But anyway, I also thought maybe my penis is too big for her. I would appreciate if someone could give me some info about what they think this is.
