I am almost 13 weeks in my 1st pregnancy and believe that I have experienced my first “heartburn” yesterday I ate spaghetti sauce, and around 4 hours after I threw up, and my chest and throat started hurting a little bit after that. Then before I went to sleep once again I threw up, I’ve been pretty much like that today as well, and my chest hurts, and even swallowing my food makes it hard. What can I do to cure it? Also, when should I be concerned about it?
