I had unprotected sex with my boyfriend in the beginning of May. He came inside of me. I took the plan B pill. My period came. I waited about 2 weeks. Had unprotected sex again (I KNOW) and then had another period but it wasn't "bloody". More like a brownish discharge that lasted a week. I haven't had any symptoms except I think my stomach's bigger and and I get nauseous when I don't eat (which is normal for me). I have been having a yellowish, "curdy" thick discharge that has a weird smell to it. But I haven't had a period since and I normally have one every couple of months but I'm getting paranoid. Could I be pregnant?
