Shaving legs, restless/twitchy legs

Stephanie • Mom of 4 kiddos, 1 boy & 3 girls (a set of twins in there) with #5 due in June 2016.
So I normally shave every 3-4 days. At the beginning of the pregnancy I had extremely itchy, twitchy, restless legs that seemed to be 10 times worse after I shaved. So I stopped shaving. That was 2 months ago. I'm 16 weeks 5 days now. I fear most of my weight gain may be from leg hair. I want to shave now but I'm afraid it will cause the twitchy legs to come back. Anyone else dealt with this?
