Pain shooting up after sex

I was having sex not even as rough as we normally would do and I was very much so lubricated by a lot of forplay but the second he went in and got all the way in it was like a stab and then the rest of the sex was normal no cramping or uncomfortable and I was laying down for a little bit afterwards and was completely fine but the second I got up to go do my pee after sex I felt a jab in my vagina that shot up and it cramped for a few minutes after that. I’m no longer in pain but just curious if this could be normal cuz I normally never have pain after sex or during sex and normally we are a lot tougher then we were today
