Its stomach acid. That happens when you puke on an empty stomach, so even if you throw it up just make sure to eat something. I had awful morning sickness and it happened to me quite a bit
Probably stomach acid it's the nastys taste yuh have ever tasted? If yuh thru up water to most likely was that I throw that up all the time say I eat go number #2 in the bathroom and later on throw up because I went #2 I don't have anything I ate to throw up so I threw up acid. It happens to me in mornings and I hate it
Probably something you ate that did you no good and since it's mixed with your stomach acid it came with that taste. I doubt it's anything that has to do with baby.
Your stomach probably hasnt gotten rid of all of the bad food.
