Birth control

Hey girls!

I recently started BC (Sunday) and I was on my period when I started. Well today I started bleeding again and I’d stopped two days ago. Is this normal or should I be concerned? It’s associated with some cramps and my skin is going crazy but overall I feel fine.

I’m also on antibiotics at the moment if that makes a difference. It’s not due to sex, because I’m a virgin but I’m freaking out a tiny bit.
