Post partum headache

I have my 2 week appointment tomorrow but I figured I'd ask you ladies. Anyone else have a headache regularly after birth? It's not a bad one, just kind of annoying in the front of my forehead. I had an epidural and also pitocin and magnesium sulfate for pre eclampsia. Don't know if any of those could contribute to this? I do get migraines but that's not what this feels like.
