I'm so scared 😭

okay so about 2 weeks ago I ran out of birth control pills and I haven't gotten them refilled yet but I'm scared that I'm pregnant?? Seriously so scared. But last time I had sex I was still on it, I had just taken it that day and I was on my period so it was a sugar pill. I had an awful headache today, my nipples are super sore (but I'm a DD and I've been wearing nothing but sports bras for 2 weeks), I feel a little nauseous but I just recently got over a stomach bug. I'm too scared to get a test, I live in a small town and someone will tell my mom. Pleae help I'm begging, anything you know, something else that it could be, just emotional support
