Chest Pain and Pregnant

Hi.  I am expecting my second child and am about 6 weeks along.  I have panic disorder and was suffering with undiagnosed chest pain for over a year.  I have had several occassions where I was taken to the ER with a heart rate above 130.  I have been experiencing more chest pain recently and am starting to get worried.  I also have had undiagnosed abdominal pain for a few months and was hospitalized twice for it.  Everything is on the left side.  Sometimes I get pulsating in my abdomen and extreme headaches behind my left eye.  Any ideas?  Anyone.  I have read that women normally have abdominal issues that are associated with the heart.  Has anyone else suffered like this?  I am worried about my health and the baby.
