So about a week ago I found brown discharge on my undies and immediately I thought implantation since the only time this has happened was when I was Pregnant with my daughter. Usually my period starts with no brown discharge. Anyways. The discharged continued for about 4 days then stopped and now nothing now period. Idk what to think, took pregnancy tests and all negative. And my periods have always been weird so I can't track them. No birth control either.
