very scared

i had sex for the first time on January 21. he wore a condom and pulled out. we just recently had sex again on Friday (February 2) and we had 2 rounds. the first time he wore a condom and pulled out, he went to the bathroom and "dealt with it" and then maybe an hour or 30 minutes later we did again. he stuck it in without a condom the second time for like 2 minutes and then I made him put a condom on. he pulled out but the cum was inh the condom, however it did not get on the outside. i normally start the first Monday of the month (today). i know it's not time to worry yet but I still am. what are the chances of me being pregnant ?
