Ok, 2 nights ago after intercourse I went to the bathroom and purple brownish discharge came out, thought it was a sign of me starting which I was wondering cause I don't usually start until the end of the month. Next morning not blood no discharge. Im 26 with 2 boys 9 yrs and 2 yrs old. Anyone have any suggestions what the discharge was for? No bad cramps like period.
