I too at the begining of my pregnancy had alot of acne especially on my back.... then it finally cleared up at around 14 weeks and now it's all back at 25 weeks boo.....
Mine was horrible! I looked like i was 13 years old going through puberty but worse! I stopped using medicated washes and lotions when i got pregnant to avoid any possibility of harming my baby. I did start to put lemon juice on my face every night after i washed my make up off. It helped so much. Make sure you rinse it off after 30 seconds. It lightens acne marks and dries out pimples.
