Should I be worried?? Or am I overthinking/overreacting??

I have REALLY bad anxiety, and I'm worried about being pregnant. My boyfriend and I have had protected sex a few times this month, and he has NEVER finished inside me.... about two weeks ago on day 9 of my cycle, the condom broke while we were having sex on and we stopped immediately. I'm just worried that I can somehow be pregnant. Do you guys think I'm okay?? My boyfriend seems pretty confident that I'm fine but I really need reassurance.
