Epilepsy and Pregnancy.Please help?

Its quite a big story.So pls have patience.OK here is what happened

Two and half years ago i had a tendon tear in my big toe.I got a surgery done to fix it.While i was in treatment my childhood epilepsy which disappeared when i was 11 years old triggered again.I have absence seizure (unconsciousness for a few seconds & no fits or anything like that). I went to a neurologist in India and he asked me to take tegratol for 2 years i did so and stopped after that.but i came to the US before 2 years.So i cud not see a neurologist here before stopping the medicine.But now that i am pregnant @ 23 years i had to tell my doctor about my epilepsy as all my friends scared me that something might happen.So i went ahead and told the doctor about what happened.I havent had any seizures since then.But unfortunately i dint bring my EEG from India when i came here.Now i took an appointment with a neuro here in the US.But they asked me if i have any of my previous records or anything.I am scared about how much it cud cost if they had to take it again.my insurance is with cigna.can anyone help me.
