Is this normal??

BF and I have sex regularly once a week twice and week but I've had my period for a while and today after 9 days I'm finally off. We had sex but I'm so sore now... I mean I guess it's just bc we haven't done it in a while and he's larger.. Idk is this a bad thing? I've also been getting kind of sick mid eating. Any of this have anything to do with pregnancy?
