itchy hands and feet??

I'm 13 weeks tomorrow but have been having mild itching on palms of my hands and fingers and my toes/soles of feet. I have occasional itching on breasts and tummy too but it isn't persistent like on my hands and feet. I will add that it isn't all day and night, just randomly through day and I will itch this one same spot for about 1-3 hours then it goes?? Doc says it doesn't indicate anything serious at this stage. Just wondering if anybody else has had this?
