Rubber torn! Cousin cums without pill in me!

The other day something happened extremely stupid to me! After a long time my cousin was visiting and we talked about old times. He was in my room and we were supposed to just come down to dinner. I do not remember exactly how it happened but suddenly we started playing around violently and I wanted to feel him inside me necessarily. Just that day I forgot to take my pill. But I wanted to have sex anyway only with a condom, so that was no problem at all. Everything was extremely horny and as he cums then he looked at me suddenly totally shocked! Oh my God, this rubber was torn and I could feel how his sperm ran from my little pussy ! Oh, what am I doing now? Do I need to take a pregnancy test?
