First time mom and labor

Ka

Good morning ladies,

I am a first time mom as the title says and my due date was yesterday with no real sign of baby coming other than Braxton Hicks. However, I've been up since 1230 this morning with a pretty bad constant pain that sometimes turned sharp on the right side of my stomach and the right side of my back. I've been throwing up and having diarrhea as well. I thought maybe they were contractions but I have not experienced any tightening or period like cramps. It doesn't appear my water has broken, no bloody show, and I've barely lost my plug. Sometimes I would feel a quick tightening that would last for a second or two on my right side but nothing worth timing. I seem to be in more pain when I lay down. Has anyone else had something similar to this? Could it be something I ate for dinner? Should I call the doctor even though I have my weekly appointment today? I'm not sure what to do. My hospital is an hour away and I would feel silly if this ends up being nothing but at the same time I'm in pain and exhausted for being up all night.

Thank you for your help and advice!
