Chiropractic care can make a huge difference. I'm only five months but my hips wouldn't be working correctly by now if not for my chiropractor. My pain started at about four months.
At work, I'm on my feet 95% of the time and lots of walking...I'll be 37 weeks on Monday. When I experience the pain I tried to slow down on my walking and they just go away. Try to keep moving even though it ***** sometimes :)
I waddle/hobble my way around as little as possible now - but I'm about 35 weeks. Pillow mountain is no longer effective...I toss and turn from side to side at night...I try luke warm baths with epsom salt to try and soak so my hips/pelvis/groin stop hurting, but they only help a little!
I wish I had better advice, all I've gotten was "Take it easy and just get through it" lol - Easier said than done right? At least we're almost there :-)
