I'm not sure whether this is pregnancy related or not. I haven't experienced any swelling so far, but yesterday after being on my feet for maybe 2-3 hours I noticed this discolouration on my foot. It mostly goes away if I sit or lie down and I still have it today, after hoping it would just disappear overnight.

It's nothing related to a strap mark from flip flops or similar as I wore lose fitting sandals and the strap doesn't sit there.

Anyone experience similar before?
