My leg sunk in? I didn't press on it or anything. Has anyone else experienced this?

Ask your doctor but pretty sure your body is retaining water it's called Edema. I had a patient with it and if anything tapped her leg she would get a dent

My leg did this too! I think it's just swelling that's why it looks "dented"

Yeah it's normal. Just elevate your legs and it should help

Pitting edema can be normal in pregnancy, but it can also indicate pre eclampsia, which is quite serious. How is your blood pressure? Are you having headaches or floaters in your vision?

I'm 34 weeks. Was at my ob office 4 days ago and blood pressure was fine
