Rib and Upper Abdominal pin with BH. Contractions

Alexis • Mommy to 31 week preemie twins ❤️❤️

I am 30 weeks pregnant with twins. Ever since last night I've been having BH contractions. They aren't always painful but sometimes my whole stomach feels like a period cramp. I am also experiencing sharp rib pain and upper abdominal cramping with them not super severe but it is enough to bother me. I have been getting BH every time I stand or laying back like reclined, the babies are also moving a ton in between which gives me relief. I have used the restroom twice today so I know it's not that and I have also tried to stay well hydrated. I also have heartburn everyday so I know this feeling isent that. I had them a lot this morning and I was going to go to Ob triage because I was right next to the hospital I am delivering at which is 30 min away from my house. But they suddenly stopped. Now they seem to be returning. I don't know if it is normal or not. I am currently in the process of switching obgyn because we just moved so I don't have anyone to call to ask. I live right next door to a hospital with labor and delivery if I think it gets bad enough. I'm just nervous I'll go and it won't be anything serious.
