Vomiting At 37+2!

Rhiannon

I woke up at half 3 this morning with severe stomach and back cramps and I just threw up from no where?! I mean it was my entire stomach contents. I've been sick three more times today but I feel compleatly fine in myself. I get nausea just before I throw up and I've got dull lower back pains. I had a scan yesterday and the doctor said she's compleatly engaged and can't get any lower in my pelvis? Should I call and let them know I'm throwing up?
