Anxiety, help

Madeleine
Hi, my name is Maddi, I'm 20 and I have a boyfriend who hasn't been with me that long but we have sex. I'm on birth control but don't take it at the exact same time everyday. We don't use a condoms but he does pull out, anyways, I'm just getting anxiety that I may or may not be pregnant. My period comes in like 5 days.....Do I have anxiety for no reason?
