July of last year I had a daughter born with several holes in her heart, VSD, and aortic coratation of the aorta. Since than she has had two open heart surgeries and nothing genetically was found worng. I was taking lamictal 200mg and vyvanse 70mg. I found out I was pregnant Nov 2010 stopped the vyvanse the very next day, but was told to continue taking lamictal. The doctors say there aren't studies that prove lamictal causes birth defect and there aren't studies that say it won't. If I took legal action would there be any real case??
