put moisturizier every day. i had chest rash in first tri and then arm pit rash in second tri. it will be itchy , bear with it and put moisturizer. i used qv egoderm on severe rashes spot and mositurize the entire chest with qv or basic aquacream. it will go away but must be patient. if its super itchy i put mopiko or any cream with cooling minty effect that reduces itch can make it a fun bonding activity by asking your husband to help u rub it on :)
how about pregnancy body oil?
