Dr,I am 12 weeks pregnant and my neck is getting very dark and is very itchy as well.I had this problem in my last pregnancy as well, but at that time doctors didn t do any thing and it got very worse postnatally and one doctor gave me tretin cream and one other cream to use alternatively during day & night.that helped to a great extent.she asked me to continue HH lite cream for 2 months, but soon after i started it,i became pregnant and i stopped it myself.I tried to contact her,but not succeded as I moved my place.Please advise me in this situation?
