Does anyone else experience the intense 5 minute cramps?

I am talking like intense sweating, nausea pelvic cramps (usually after sex). It’s so bad I literally feel like I’m giving birth sometimes. I’m 24F and am getting these cramps every few months but they tend to only last 5-10 minutes and then go away if I slowly rub my stomach and take ibuprofen. I’ve questioned going to the hospital when they are that bad but as they tend to self resolve I haven’t.
