Rebecca,
Your epilepsy should have no ill effects on your baby's health. The only thing that I can think of would be falling, but anyone that is pregnant has to be careful about that.
Your baby will not be born with epilepsy just because you have it. Your baby will have the same odds of getting epilepsy as any other person. Go to the link that I have below and it should ease your mind a little.
