I've been on birth control for almost a year now, and I'm recently starting to have this thick brown discharge instead of what it normally is. I'm kind of worried because this has never happened before. The last time I had sex was on New Year's and that was 3 weeks ago, but my boyfriend used a condom, pulled out, and I was on the pill at the time. I've heard brown discharge could be a sign of early pregnancy but I'm not sure.
I'm also feeling queezy but I figure that could be from feeling sick to my stomach about being pregnant...

Does anyone know what may be wrong?
