Hi all, I noticed this on the back of my legs a few weeks back it's not painful or anything but I've been having headaches a lot this pregnancy (I'm 18 weeks) now I'm convinced I'm some sort of clotting! Has anyone else had anything like this? Could it also be varicose vein related? My mum has them bad and I have a small one on the same leg, so not sure if it could be that x
