Hello! I m currently worried about being pregnant. I have been on birth control for about a year and a half now. This last month I extended my hormone pills an extra week because I didn t want to have my period during a specific event I knew was going on. During that event I ended up having sex and it was unprotected. I am slightly worried about being pregnant because I started taking my water pills this last week. I waited till day three into them (thats when my period usually starts) and all that came out was brown discharge. At the end darker red blood came out, but not much. Is this just old blood because I pushed my period back a week, or is it implantation bleeding? Could I be pregnant? Thank you for the help!
