i am 27 weeks, I just had a very stressful evening filled with lots of tears and stressing. I am now not able to catch my breath, my heart is racing, and I have felt some sharp pains in my stomach . I also threw up twice, and I have not thrown up at all my entire pregnancy. I am worried about my baby, i know stress is bad for them. I was debating on checking myself into the er....should I, or am I just over reacting?
