I am only 4 weeks 4 day pregante from my last period. Well my feet are already swollen and hurt alot. On both feet I have blisters starting on my middle toes and ring toes. I have had the same shoes for month and same socks for a few weeks now. I have had no problems with them until this passed Friday. Now my feet hurt so bad i can't have socks or anything on them. My feet are also really dry to. They are not cracked dry but dry. I just don't know what to do.
