TMI question

Me and my fiancé had sex last night he always tells me how wet I am. And ( sorry tmi ) it always slides right in with no pain. Well 4 nights ago when we had sex it felt different like my vagina was swollen or something it was hard for him to go in and it was uncomfortable. Last night I asked him if it felt different to him and he said I’m still wet but the wetness feels different. Which I agreed and he said he noticed I said it’s a little uncomfortable if literally felt like my vagina was swollen. Any opinions going to call my doctor !
