to start off, i’m 17 and have been with my boyfriend for 3 years. my last period was june 14th. we have had unprotected sex alot and im not on the pill anymore. ive been getting nauseous, my boobs are swollen and i cant touch them! ive been peeing alot, super tired, and am now 4 days late for my period. exactly a week before it was due, i noticed a tiny amount of dark brown blood, only lasted two days. i took 2 tests last week, both negative. any advice on what i should do ?
