my gf and I are worried because she feels that her breasts are tender and we haven't been doing anything sexually for awhile. she finished her period on the 1st of april and we havnet done anything since the 8th. we had unprotected a few times but i only had my penis in her for 2 sec and we only did it 3 times. we were messing around though the day after her period ended and some might have gotten around her vagina, but i read that a women usually ovulates around day 12 to fourteen and the sperm usualy die out in 5 to seven days. but we are worried and we were wondering what are the possibilities for the tenderness and she feels like she is going to get her period again because she has lower abdominal pain like she is going to get her period. any help or suggestions would be great thanks.
