27 weeks leg pain circulation issues? Looking for good support leggings

I am 27 weeks pregnant and already getting some lower leg pain. I also have a few veins that popped up on the back of my leg (varicose) that are tender to touch. I am looking for suggestions on good legging,hose, and or anything to help with my circulation. I try and be active about 4 times a week, i.e walking or riding stationary bike. This past week I have been really sick so not much of anything. I also have been trying to sleep on my left side. Thanks!
