Birth Control
"I have been on Errin norethindrone tablets for almost five months now and have liked it a lot more than regular birth control tablets.  I gained a lot of weight on birth control with estrogen and have not on Errin, which I liked. But, it has not helped acne like my old birth control.  I also haven&#039;t had a period since the first week I took Errin, which is somewhat concerning, but I&#039;m not pregnant, so I assume it is just my body getting used to the medication.  Errin has not effected my mood or mentality."
