"taken this birth control for 3 weeks now. just started the period week with no period. my breasts have grown and were extremely sore for about 1 week. my face has broken out horribly in the last few days. in a matter of hours! i usually don&#039;t get acne but this pill has caused horrible breakouts all over my face. it has also made my face oily. i will give this pill another month or so, hopefully this side effect will go away."
