Weird cramps??

El

So my period ended on Monday and it was a bit shorter than usual as my period normally lasts 5-8 days but it’s only lasted 4 days. And I always get cramps during my period but I’m still getting cramp like pains after it’s ended and this never happens. It’s hard to explain what they’re like because they’re not like cramps but they are at the same time? They last as long as cramps do and it would just hit me randomly for a few seconds but they’re not too severe, they almost feel like trapped gass but lower down where I’d usually get cramps. Does anyone know what this is?
