So I was out all day yesterday at a water park in 100 degree weather, I'm 31w2 days I kept hydrated, sat when needed but I still think it jus took a toll on me.. I've been getting random bouts of nausea for the last few weeks, my dr assumed its "morning sickness" creeping back. Well I also have IBS that I've been battelinf for years and its gotten worse the last 2-3 months. Well today I was at the store with my daughter & got extremely nauseated, I got some water and still needed a zofran.. Well then I had to have a bowl movement. I went to the bathroom and it was green .. I know tmi and I apologize... But what could that be from?
