Hey I have epilepsy, I actually have Petit-Mal epilepsy, and in the 15yrs I've been treated for it, I've only had three seizures. My epilepsy comes in the form of "absences" my eyes and mouth flutter, and my brain faints for seconds. I loose all awareness for seconds. It can be quite dangerous, I did this once when I was crossing the main road!
I take Lactimal, I've been on it since I was 16yrs old, mostly because I had a wonderful consultant, and he thought if I were to get pregnant, it was the safest tablet for me and baby. Prior to taking this, I was on Epilem, which is only prescribed to children. I am now 16+2, have a healthy baby, growing quickly, and I am still on Lactimal. I take quite a low dosage, but I feel comfortable knowing that it's safe. It's even safe to take during bf.
There is some conflicting advice. I would wholeheartedly suggest speaking to consultants over your GP. I have a lovely GP but she was adamant that I should come off my pills when I fell pregnant, which is something I was really against. It made me feel really vulnerable. So she prescribed me 5mg of folic acid, opposed to usually shop brought 4mg, and I went to see neurologist. GP said there will be developmental delays...there is heightened risk, but if you don't take tablets, you are at more risk of hurting yourself and baby.
It's very important that more than any other pregnant lady, you look after yourself. If you are tired, go to bed, if you feel the possibility of a seizure coming on (the only three I've had, I could feel coming) lie down, breathe slowly, and try to relax. It can be scary to think about epilepsy, but it's manageable!
With regards to birth, I've been called high risk in my blue notes. So home births, and possibly water births are out. I still plan to have a natural birth though, just in hospital. Unless your epilepsy is fairly severe, I wouldn't assume c-section is your only option. Speak to your midwife about this.
