I had a new experience last night and was woken up from a dead sleep with what felt like a tightened abdomen and a burning pain below my sternum (which I hear might be heartburn....?). I felt awful and got up and threw up everything in my stomach. After that, everything calmed down, and I felt the baby kicking, so I decided to hold off on calling my doctor. I'm feeling mostly normal this morning, but was wondering if anyone else was experiencing this as well. I'm about 24 weeks.
