I’m nervous. Not trying to have one. Not right now 😭

So... i had sex on october 14 with my boyfriend. It was my first time. It was unprotected, he didn’t cum inside me and we didn’t fully do it. Then 3 days after i had my period it was on october 17 it lasted for 7 days. And then after having period... the next day october 24 i started to have cramps... it lasted for an hour or less... and i’ve been having it for a week now... i hope i’m not pregnant 😭 im kinda scared. Is this just a feeling or what?
