Vaginal cramp on toilet

Sorry, TMI, but anyone else experiencing the worst vaginal cramps when going to the toilet for a number two? I just try to relax to be able to go and then it shoots right in, just like a leg cramp. I need breathing techniques to get relaxed again. Than it disappears after a few seconds, but if I’m not done yet sometimes I get one or two more. I have this already from first trimester on and I had it also sometimes when I had the mirena, so maybe it is something hormonal? 🤷‍♀️ It hurts like hell.
