Brown discharge?

Kenzie
I had sex while on birth control and we used a condom. I'm just freaking out about it. I took my first sugar pill today and was thinking I was supposed to start my period and I am super worried Bc I didn't!!! Is it supposed to start the first day of the sugar pills? Also, I have had brown discharge a couple days before the sugar pills. Is this normal? This is only my second month on birth control. I'm worried about pregnancy, but I'm a worry wart and since he pulled out, used a condom, and I was on birth control for over a week I think I am safe. (I hope).
