Not trying to be rude but if you don't want to get pregnant why have unprotected sex ma? But the only way you will know for sure is to take a pregnancy test hope all goes well...
Yes you could be pregnant. You can get pregnant anytime you have sex whether protected or un protected. But especially unprotected now with that said you would have had to ovulate late in order for you to be pregnant. Take a test to find out.
All u can do is wait and see take a test a few days before your next pd.
Its possible if yu ovulate late, but I think its very unlikely
