Taking a bath?

I want to take a bath so bad!!!! I know you're not supposed to but its winter and very snowy where I live and my skin is so dry it's itchy so I've just been wanting to take a bath so bad lately. I've heard if its warm it's ok, but not hot enough to raise your body temp. Has anyone's doc told them it would be ok or given further info? I'm almost 13 weeks right now n my doc appt is in 2 weeks so I'm gonna ask then but for now I was curious to see what others say.
