Pregnancy Feet?

Recently my feet have started itching like crazy. My dad is a medic and told me that it doesn’t look like athletes foot..my feet hurt when I walk barefoot on the floor and there’s a major difference as soon as I put socks on. My feet are cracking like crazy and there’s a ton of patches where all my skin is crazy. Most of it is on my toes and heels which is where the pain is when I walk. The part that itches is the middle part of my foot. My dad said he’s got no idea what it is that I should ask my doctor. But I don’t have an appointment for a while and I was wondering if anyone else has had this happen or if they know what it is? I’m 32 weeks pregnant and I used to be super tiny and I haven’t gained a HUGE belly like normal people but it’s definitely huge compared to my normal size so my dads thought was maybe it’s because my body isn’t used to the weight.
