37+3- Flu like symptoms?

I went to my OB yesterday and she checked my cervix. I was only a fingertip dilated and only thinned out a little... But ever since then? I've been achy, cramping, stomach has been hurting and I've lost all appetite. I had to force myself to eat French fries yesterday and ended up throwing them up. I ate a small piece of cake and drank some water- and at 5am, threw that up. I've had loose stool (Sorry! TMI) and I've been just groggy, exhausted and pukey all day today. 

Is anyone else going through this? I'm just... I really want to feel better.
