Pregnant with epilepsy

Hello, I just joined and I wanted to introduce myself. My name is Heather. I have 3 kids. DD is 8, DS is 6 and DD is 7 mo this old. About a month after I had my youngest I had a grand mal seizure that put me in the hospital for 3 days. I was diagnosed with Epilepsy. I’ve been having about 15-20 seizures every hour for a very very long time. I just found out that I’m pregnant with my 4th. I’m so scared. We knew we wanted another child, but not this soon. My seizures aren’t fully controlled yet. What if it hurts the baby or the meds? What about my youngest DD? I’m so stressed and scared about the entire situation. Anyways, thanks for letting me vent about it. I’m not telling anyone about it for a while, so this is the only place to talk about it.
