advice needed

So I'm on birth control been on it for like a year now and take it everyday at the same time. Although i'm having a bit of anxiety because I had sex on the last day of my period and he pulled out but some cum still got on my vagina. I cleaned it up fast and peed after but I feel so anxious. And then I had sex again yesterday which was a week after the other incident and this time he didnt even cum. Am I being too worried ?... I havent missed a single pill but took one a little late a couple days ago. Please ease my anxiety lol he says I'm just trippin but idk I need girl advice.
