Anxiety

I’m on the pill and take it perfectly but lately my anxiety has been killing me. My boyfriend and I have sex pretty often but he never finishes in me and pulls out way before. I’ve taken a good amount of tests they all say negative and my period is due in 5 days. My period last month came on t he day it was supposed to but seemed kinda light (I was on antibiotics the week before) but I did bleed for 4-5 days. I’ve been having lower back pain and this bloating left pain in my side/lower ab. I don’t really have any other symptoms but my anxiety has been killing me and I’m worried I won’t get my period. I can’t tell if I’m overthinking it or what but my mind is playing tricks on me. What are my chances of being pregnant ?
