accidently took my depakote twice within four hours.

im pregnant and im up kinda late tonight because i couldn't sleep due to heartburn. so when i finally got sleepy, i walked to the room and realized i forgot to take my prenatal and my folbic pill, so i grabbed my two medicine bottles, not thinking and took my folbic pill and took my depakote instead of my prenatal. they're both big pills and i was sleepy and i just took my depakote at 10:20p.m. and i just took it again at 2:50a.m... on accident of course. has anyone accidentally taken their depakote twice within a couple of hours? if so, will i be ok? and is this bad for my baby? ~~concerned epileptic mommy to be~~
