Help me cope with stress

Sarah

Okay so I had sex with a condom a month ago and I had my period 2 weeks ago. My mom just found out recently that I’m not a virgin anymore and she asked if I was pregnant. It got into my head and everything and I’m worrying myself that I am even though I had my period. Last week I had brown discharge and everything and that is what made her ask if I was. I’m still worrying about it and it’s Monday. I mean if I was I would’ve had symptoms by now right? I’m just over reacting and just need to know it’s okay because I really don’t like sharing with people at school or anything
