Do you mean like someone is stabbing a knife up and into your cervix through the vagina?
I had this before I found out I was UTD this time and told my OB and she said not to worry unless it happened again. It only happened for like 2mins and didn't occur again.
It was really uncomfortable and I was squirming in my seat and DP asked what was wrong so I told him and then it went away.
If it happens again may be go get checked out, better to be safe then sorry. Or call the pregnancy and babies health connect line and see what they say.
GL I hope its nothing!
