2nd tri m/s onset?

bluek210

I had the easiest first tri barely any nausea, decent energy , etc. I'm now about to be 14 wks, and for the last week or so i have been nauseous almost every day, vomiting every other or so, plus occasional diarrhea and insane gas cramps. WTF? Is this normal? I feel like I'm getting payback for being so lucky my first 12 weeks! Ugghhhh!
