I have epileptic seizures and I am pregnant. I need insight..

[melie4]

am a 24 year old women and pregnant with my 4th child. As a child I had grand mal seizures. Around age 5-6 I stopped. Then in 2009-2010 I became pregnant with my first child. That's when my seizure came back. Every since then I have had them with all my pregnancy. With Every time I get pregnant they begun to get worse. With this being my 4th child I have in the last week had 2 within 5 days with the first one being over a hour in critical condition due to not being able to pull me out of it. Then give days later I had one with my blood pressure was 140/0.  I take keppar 1000 mg twice a day with 4mg floric acid. Every time I have a seizure my left arm and hand is numb, and I can't hold anything with my left hand without dropping it with pain shooting up my arm. But my arm is numb 85% of the time for days after a seizure.what is thus or is there a underlining issue..
