I was supposed to get my period on September 8th but I didn't get it until 7 days later the 15th but the thing is that I had unprotected sex the 13th and my bf ejaculated in me . Okay well I had my period really heavy for like 4 days then later the 5 and 6th day was really heavy watery dark brownish discharge and like two.days later I noticed pinkish heavy discharge. Is that normal?
