Cramping right abs ... for hours

Mommies. Im 26 Weeks & was so close to going to the ER at 1am ... I was in so much pain. But baby was sleeping, we're in a hotel in another country, so I just tried to sleep through pain. It was all cramping on my right side. Like huge "pulling" feeling, almost like something burst or popped, it was weird. and it lasted like over 6-8 hours. I woke up this morning & still feel it a little, definitely cramping feeling. Any idea on why it would feel that way for so long? And if that's normal... No matter what position I was in, the cramping was so painful 😖
