Leg Pain

Lacee
I'm really at a loss here and not sure what is going on. I am 19 weeks and For two days I have had leg pain in my right leg. It's in my thigh right above my knee and has felt like a cramp and hurts worse when I walk. It started yesterday and I thought I may have just slept weird. But I have taken Tylenol two days in a  row now and have taken a warm bath and used a heating pad as well as using a pillow between my legs when I sleep and keep it propped up when resting. And now I am at a loss. Any ideas mommas?
