Leg pain 10 weeks

I was wondering if anybody has been experiencing any type of leg pain? I'm 10w 4d and have had a consistent cramp in my calf that moves up behind my knee and into my thigh. One of the pharmacists I work with said to call my OBGYN immediately because it sounds like DVT, but when I looked up the symptoms it sounds nothing like what I have. It's just a consistent ache. I'm not in awful pain, it's more of an annoyance. I'm also noticing my legs are falling asleep much easier than they used to.  I didn't experience anything like this with my first pregnancy 6 years ago, and my husband already thinks I'm a hypochondriac, but I don't want to overlook something that might be serious.
