My psoriosis inproved heaps during pregnancy, I had decided to not use any ointments etc either.

But now my scalp is nasty - has been where I have been getting it the worst in the last few years, I had a flare up on my LHS bbs (never had it there before, but a couple of days of ointment and seems to be holding it back), also got small patches on my elbows and RHS knee, but not enough for me to worry about IYKWIM.

It improved a few months into my pregnancy, I reckon end of first Tri was when I really noticed the difference

HTH xxoo
