Hi I'm 18 weeks pregnant and this mainly happens when I've just ate, or am in the process of eating I can feel wind come up but it pushes up the food along with it and I start vomiting, I don't think it's acid reflux because acid doesn't come up its literally just the food I've just eaten that comes up, it happened to me tonight when I was halfway through a meal and now I'm so upset because i was enjoying it so much, once I finished vomiting I just finished off my food but I didn't feel satisfied after I was really enjoying that like I haven't enjoyed anything as much in such a long time ðŸ˜
