I'm 24 years old. My last period began on dec 19th and ended on approximately the 28 or 29. My husband and I have sex quite often and we don't use any kind of contraceptive. My period was supposed to have begun yesterday and it's not here. For the past two weeks I have been feeling really sick. Had white vaginal discharge, very nauseous, tired, lots of headaches and I feel super bloated. I have some tingling in my breasts and my lower pelvic area. The first pregnancy test I took had a faint line , I took three after that and they're all negative. Idk what to do?
