condoms

Me and my boyfriend were having sex, and he was wearing a condom. He had to change condoms inbetween because one ripped. Anyway, he asked if he could finish inside me and I said I think it would be safe because he is wearing a condom and because I take the pill. When he did, ya'know, there was a kind of weird warm feeling, I'm just wondering if this might mean sperm got inside of me and if I should be concerned about pregnancy (I'm on the pill but j like to play it extra safe)
