i have had posion ivy on my stumach for the last week or 2 and ive almost gotten it cured with calomine lotion. but im 7 months pregnant and i started to get some type of rash on my personal area. it itches horably and is sore where i have scratched it.. CALAMINE LOTION DOES NOT HELP. its swollen and bumpy. but when i pit A and D ointment on it, it stops itching and hurting. what could this be?
