I had unprotected sex the 4th week in February.2 days later I noticed that I was bleeding.It lasted for 3 days.My menstrual usually comes the last week of ever month.Its like it came a week early.I assumed it was my menstraul and
didn't think anynmore of it.Two weeks later I noticed that I started to have lower backaches,low abdominal pain,headaches,frequent urination,feel nauseous in the morning,and I started to feel dizzy sometimes.I have been feeling like this 4 weeks.This month my menstrual came on at the correct time.I noticed that I would wipe with a tissue and there was dark brown blood on the tissue.I decided to put on a pad just in case.The firsr day there was nothing on the pad.The next two days it was this dark brown blood.It was as if it was almost black.The fourth day it was light pink.I haven't took a pregnancy test because I don't knoew what's going on.Help me please!!!!
