So worried

Ic had epilepsy my whole life and when I get pregnant it gets worse because the baby takes some of my medicine away from me. I have one daughter that will be 2 in August and is perfectly healthy. I am 23 weeks +6 days today and I’m so worried that I’m going to lose this baby. Iv never had a misscariage thank god. I do feel awful for the women who experience that. I am just worried because my epilepsy was bad with my daughter when I was pregnant with her. But it’s much worse with my son and I don’t want them giving me anymore medicine that I’m on already because I don’t want my baby coming out not healthy. Any advise
