So Thursday night I had brown discharge, Friday morning i had brown discharge and then by the afternoon nothing, Friday night i had actual blood when i wiped, Saturday morning i had brown discharge when i wiped and some brown/blackish clots, the rest of the day just brown discharge and then last night nothing at all and this morning still nothing. I am suppose to have my period yesterday according to my app but I have been as much as 5 days early or 5 days later from what it predicts I just dont normally have all this. Itll start like that the morning of but then it turns into my normal period. I have sore boobs, acne, emotional, cramping ,mad at everyone and everything like I normally do before period. I took a pregnancy test this morning and it was negative. What the heck do yall think is going on? Had anything like it? Of so what was the out come? Could a lot of sex cause my period to act werid/delayed?
