Tmi cramps

Hi!

So sometimes I get this weird cramping feeling in my gut, vagina area and rectal area. Its like how a cramp is when you can't relax the muscles or something its honestly hard to explain but I'll try. So its like pretty painful to pee but not where I pee from, the pain is in my low gut area and rectal area mainly. I mean it hurts to sit in general and certain positions are way too uncomfortable for me, and sometimes it hurts regardless of what I'm doing. I can't really think of anything that would cause it to start, it just does randomly pretty bad and lingers for a day or two and I'll be sore for a few days after. I tried googling it but its hard to tell bc the possibilities are endless and its hard to explain the feeling really. Pretty much crippling period cramps but in my lower gut and rectal region. I know the explanation sucks I apologize but if anyone has gone through something maybe similar could you give me advice or ideas? Thank you and no I'm not on my period
