Nausea

Anybody else's nausea seem to have returned? I had MS the first trimester, was sick the second, but I think that was because of a UTI, after antibiotics I haven't been sick again. I'm 31 weeks an 4 days and have been sick and nauseated for the last 3 weeks, at least 4 times this week. It's getting worse. Talked to my Dr's PA at our visit on the 11th, she was going to get me refills on my nausea pills. Probably have to ask my OB at my next visit Thursday, I think her PA forgot.
