cause for panic?!?

Scarlett
Right I'm 15 and I've been with my bf for 7 months we've had sex. We're long distance so I only see him on weekends when I can but we haven't always used a condom but he's always pulled out and I am now 3 days late and I am not normally late. Is it just the fact I'm having sex that's changing my cycle or should I start to panic? Any and all advice would be a GREAT help rn xxx
