Hi Km, welcome! I have 3 children and took Tegretol with all 3 pregnancies. I also breastfed and took Tegretol. I'm not sure about Lamictal and pregnancy but each anti-convulsant has it's own set of risks of birth defects. All 3 of my girls turned out 100% healthy and zero birht defects. I must say that the whole time I was pregnant I was scared to death that something would happen to them because I continued to have sz's while I was pregnant. Each one of my pregnancies I had an amniocentesis that confirmed that they were healthy and because of my history of sz's the ultrasound I had was done at a higher level. When you're a high risk pregnancy, which you will be considered, you do have the advantage of an access to alot more testing. My labor was induced so that they already had me hooked up to an iv in case I went into a sz during labor and they needed to administer meds. Before you get pregnant start taking prenatal vitamins. This will give you a head start on preventing birth defects. This is especially important in the first month of your pregnancy when the brain and spine are developing. Some anti-convulsant related birth defects are spine and brain defects. It's also important that your neuro and ob work together. Hope this helps.
