Sciatic Nerve?


Im 30 weeks and wondering if im getting sciatic nerve? For a couple of weeks now half way through the night my left hip will just start aching so bad that i have to roll over and get off of if. Ive slept on my left side for years and never had this issue. The other day i also had this pain from my lower back through my butt check to the top of my thigh.

I see my chiropractor this week and dr next week so ill be asking them but just wanted to hear if this is normal or if it could be leading up to sciatic nerve?
