Morning sickness again!

I'm 31 weeks and have begun feeling nauseous again, stomach pains and fatigued like no other. The first 18 weeks of pregnancy was hell, with ER visits every other week for fluid. I'm really not ready for nausea again. My tummy has been aching since last night almost feel like I have indigestion or something of the kind and migraines have returned. Boooo!!! I feel like a grown man with the flu, just wanna sleep and boohoo.
