yes if u have unprotected sex theres always a chance you can be pregnant. pulling out doesnt work because theres a thing call pre cum with can actually get you pregnant. please next time use protection and best of luck to you
the pull out method doesn't always work as there is also pre come. that's how i got pregnant. it depends on when you ovulated. best thing to do is wait and see if your period is late and if it is take a test. good luck
