Leg pain/cramp?

Elle387

So, last night I was quite comfortably sitting on the sofa, and then when I stretched out I got a strong achey/restless/almost crampy feeling down the inside my left leg, from my bum to my ankle, but strongest around the inside of my knee. I tried to stretch it out and walk it off but it didn't go away until I went to bed a couple of hours later.

Is this the restless leg thing or leg cramps that people talk about during pregnancy? Didn't feel like 'cramp' but did feel crampy if you know what I mean?! And when I say it felt restless, I mean I couldn't keep still or get comfortable otherwise it was aching horribly!

By the way, I'm 13w 1d.
