Ugh. I had a lot of sciatic pain earlier in my pregnancy and I'm SO GLAD it stopped. SO painful. The pain that replaced it really sucks too, though! When I get up in the morning or during the night to pee, I seriously feel like my pelvis is going to break if I don't brace myself on furniture and walls on the way to the bathroom. My ankles are fine, but I would definitely think it would just be from the weight.
