Scared of being pregnant and not knowing?!

Okay please don’t call me crazy, I have severe anxiety and I do have a therapist and all but I can’t shake this one. I’m so scared of all the stories about people not knowing they’re pregnant. Last time I had sex was in April, I’m on the pill, and my boyfriend pulled out but who’s to say NOTHING got inside. I have gotten my withdrawal bleeds since then. But I’ve been going to the bathroom a lot more specially at night, the past week I’ve had NO appetite. I’ve been stressed out a a lot too so I’m not sure if that can cause night time urination. I had bloodwork done recently so it isn’t medical. Idk I know I sound crazy, but those stories are scary. Should I be worried? I can’t get to a test anytime soon due to my living situation
