pre-pregnancy i used differen and was told that it was too strong so i was given oxistat and erythromicin (sp). Oxistat is a great moisturizer and i use it in the mornings, erythromicin is for nighttime use and it has a strong alcohol smell and makes your skin peel. its not really irritating or uncomfortable since it is for nighttime use but i would tell you to be careful since you are pregnant and you may develop new sensitivities. I would also highly recommend visiting your dermatologist to find what other meds may be good for you.
