Sciatic Nerve?

Just in the past couple of days I've started having severe pain in the front of my hip (I'm 20 weeks + 1 day). I'll be walking my dog or just walking around a store and all of a sudden my hip is killing me, pain shooting down my leg and my toes go numb. I know sciatic nerves are usually in the back of your hip, but mine is in the front. I told my Dr at my appointment yesterday and she didn't seem concerned. Has anyone had this? Any recommendations to make it feel better?
