Sex and anxiety

Hi y'all! So I lost my virginity last night with my boyfriend. I've been on the pill for 6 days, and we used a condom. I, however, have Intense anxiety, like all the time, and am super afraid I could be pregnant still. That's just how my brain works. But I don't want my anxiety to get in the way of having and enjoying sex. Are there some ways I can calm myself and be reassured? I guess all those trojan horse stories really stuck with me huh. 😂
