I'm 15 weeks today. I was feeling marvelous for about two weeks, until yesterday. Around noon I had the worst hot flash. I began to sweat on my chest area and I started to feel very woozy, like I was going to vomit. I sat down and drank some water and felt better. However, ever since then I've had that feeling like I'm going to throw up after I eat and intense gas pains. They'll hurt sometimes and then I'll pass gas. Other times, my tummy has a stretching feeling to it. I'm not sure what's going in there but my body is not happy. Why did this all happen so suddenly?
