There is always a possibility, in this case very slim. You used protection and you got your period. I'm not a doctor but I am 99% sure you are not pregnant.
I had sex for the first time 5 days prior to and leading up to my period (unprotected), and he pulled out. I got my period for maybe a day and a half, and then it completely stopped can I be pregnant?
You are obviously young if you're posting this type of question.....please, don't EVER have sex that's unprotected. If you are not ready for the consequences of having sex....pregnancy being the main one.....then just say no.
