Sciatic Nerve Pain

Farrah
I know you guys aren't doctors but I'm 15 weeks pregnant not showing at all and have horrendous sciatica. I've had it before I was pregnant but rarely have flare ups. this is my second pregnancy and didn't have it with my first at all. I guess my question is there's no way it's from my pregnancy this early did anyone have this and get it resolved my chiropractor or anything!?
