I need advice!! So the other day on the 26th I went to the bathroom and I had a brown discharge almost like there was some blood mixed in with it. It wasn't much and it just lasted the day. I ended my period the 9th and the last time I had sex was the 12th. I am on birth control but it's a very low dose and he didn't use a condom. I remembered that night I had gotten sick because of birth control but it was within two hours so it didn't go through my system. I am scared because everything is lining up. I looked it up and it said implantation bleeding occurs 6-12 days after its fertilized and right around when you're suppose to get your period. I'm suppose to get my period on Wednesday. I have never had a problem with spotting like I've never experienced spotting in between periods. Could I be pregnant? I need someone else's opinion!
