Sick feeling

I’m currently 32 weeks pregnant and The last 3 days I have had a loss of appetite. My belly growls and makes funny noises but I don’t feel hungry or have the urge to eat. I’ve also had really bad gas and diarrhea. I’ve been trying to eat light meals and snacks. And yes, I’ve been drinking a TON of water. I’ve also had some stomach cramping. Not sure if it’s from all the gas or what. Cramps aren’t really time-able so I don’t think they are contractions. Having some white thick discharge as well, and it has a small odor. Anyone else have or had this happen? Any suggestions on what I should do?
