Leg pain

Brandi • Mom to an active, kind, & hilarious 6-year-old girl and a baby boy who arrived in March. Miscarriages 11/08 and 3/15.
When I was in the last trimester while pregnant with my daughter, I got horrible Charley Horses that would wake me up from sleep. (I'd wake up screaming because it hurt so much!)
I'm 12 weeks + 5 and after a night filled with bits of insomnia (up from 2-4, 5-6), I went back to bed this morning and woke to leg pain that feels like a Charley Horse. But it hasn't gone away in the last two hours. Anyone else get these? What's going on?
