What should I even be doing now? (TMI)

So, late last night I started having contractions 10 minutes apart. They're still happening, though I've been sleeping and can't honestly say if they're still just as regular.
But I also feel like I have smurfing food poisoning. I woke up like five hours after the contractions started and I've been having diarrhea, sulfur burps, and my whole middle is just sore. I'm nauseous, too. I've thrown up stomach bile a few times.
I just can't tell if it's related or something else. Neither DH nor DS is sick and no one has posted anything on Facebook about feeling ill, so I don't know if it could be something that I ate. I've read diarrhea is normal and I've had morning sickness the entire damned pregnancy. It also stands to reason that my stomach would be all cramped up, especially down in my crotch. I don't have a fever, either.
Just...what do I do? I hurt and all I want to do is lay down in bed but I don't know if I should try to get in touch with my OB again. I called maybe an hour ago before going back to bed and they never called back.

I would call. Maybe your dehydrated?

I have had all of these symptoms for over two weeks...my doc said t was just normal getting ready for labor things and cautioned me to stay hydrated and rest as much as possible. Bout days ago the contractions moved to 4 minutes apart but I'm sill having the diarrhea and nausea. Good luck! I'm 38 weeks btw...

I would just call your doctor to let him or her know what is going on just as a heads up and just lay down and stay hydrated as much as you can. Whether its the start of labor or you're coming down with something, you need rest. Good luck mama! Hope you feel better
