OK so I had protected sex about 2 weeks ago and I'm waiting for my period, which should come in about 4 days. I have never really had a period that was on time or normal. It always comes when it wants. I still still keep track of it, but I am never sure. But today it felt like I got my period, but when I look it was like a red/pinkish brown discharge. Does that mean I'm pregent? Please help!
