Ok TMI. But sunday September 21st i had started what seemed like a period. It was brownish in color but first started off kind of heavy but lightened up. Then come around monday it was still lightening up and stopped monday night. Then tuesday it started again around 4 o'clockish then stopped around 6. Then wednesday and thursday once a day it was pink on the tissue and never had anything since but clear and white discharge. I had unprotected sex sept. 3rd, 12th, && 23rd. Could i be pregnant after that i never had a period like that before
