Please help ease my nerves :)

I started taking BC the day after my period ended. 2-3 weeks after that (also, taking my pill on time every day)  I MAY have gotten cum on my vagina but I did not have sex. Then a few days after that I had brown discharge for 10 days (which I've heard is normal for being in my first 3 months of the pill especially). Then I got my period on time and it was the same as it always is ( I had cramps and everything). Is there any way I'm pregnant? I think I'm just really paranoid.
