Stomach totally upset!!

Andrea • Baby boy born 2015, excepting babe #2 in April 2019!
If it's not one stomach problem, it's another! Morning sickness started around week 5 as well as terrible constipation and food adversions. Stil having those symptoms but now I have added a mix between constipation and diarrhea. It's so awful! If I eat healthy, I feel sick. If I eat  junk food, I feel sick. Luckily I haven't thrown up but this feeling just is awful and the bathroom habits are even worse! I know it's all worth it in the end, I'm just hoping my stomach and eating will be back to normal soon. Anyone else in the same boat? I'll be 9wks tomorrow. ?
