i second that, i think u have abit of gastro. I know of alot of ppl who have had it during their pregnancies (my SIL has it really bad atm too and shes about 14 weeks) and they have all been fine. Its good to go get it checked out anyway because you dont want to get dehydrated.

Either that or u have picked up another virus. I dont think you should be worried, but still go get checked out.
