My mommy, I need help. For a few days now, my breasts have been hurting inside, but when I press them, it doesn't hurt. Sometimes I feel some movement under my abdomen, like menstrual cramps, but not painful. I took a pregnancy test and it was negative. This Saturday will be my second Saturday after I met with my husband, will it show that I'm pregnant or not?
