Period talk!

Lismary

Hello so I’m stressing out. I’m currently on birth control and sexually active. On dec.17th I got my period lasted a week I started going to the gym and changed my diet and I’ve been losing weight. However now I’m starting to get weird brown discharge is that because I’m exercising or could I be pregnant? It’s been about 2 weeks since my last period and I’m set to get my period next week.
