Has anyone experienced constant light pressure/cramps and pain during sex and found out they are pregnant?

I’ve been experiencing these dull aches/full feeling just above my vagina, all around, I just had sex with my fiancé and it was extremely painful, it’s never happened before and I’m a bit worried, I know you guys won’t know for sure but just seeing if anyone experienced something like that, it’s still a bit sore afterwards.. :)
