Please help!!!

I feel like I might be extremely paranoid, but I always am.. Me and my boyfriend had sex last weekend (the weekend before last) (quite a few times) and then I had my period 2 days later and then my period ended like 3 days ago and me and my boyfriend had sex twice since but we used a condom each and every time and now I've got so many pregnancy symptoms but I can't possibly be pregnant if I had my period right? I'm probably overthinking it but I'm genuinely petrified.. maybe its pms symptoms? My period usually affects me pretty bad leaving me with bad symptoms before and after.. ahhh I don't know!

Also I only lost my virginty this month so I don't know if that makes a difference with tender boobs and stuff! (Im 19)
