I get it on my scalp too with the odd little spot on my body but you may find you wont need to use anything on it during your pregnancy.
All 5 of my pregnancies it has cleared up completely. Apparently you produce a hormone while pregnant that helps clear it up so fingers crossed this is the case for you too.
It doesnt last long and comes back soon after I have had the baby but it is lovely not having to worry about it. You would think that they could somehow reproduce the hormone so we could take it after been pregnant. Hmmmm sounds easy enough :lol:
