Shooting pains in hip and thigh!

Katie • Expecting my rainbow baby Jan 2017 ❤️
Last night was the worst nights sleep I've ha to date whilst pregnant. I've had sensitive skin on my thigh for a while now but since yesterday it's gone all the way up my leg I've been having shooting pains down my thigh and in my hip! It was horrible :(! I read that it may be a sciatic nerve but I'm only just 12+1! Does anyone else get this? :(
