I was switched to Micronor because my insurance didn't pay for the birth control containing estrogen. Since starting micronor I have not had any bleeding. I do how ever have mood swings and bloating and nasuea about every 28 days. I take it everyday at 9pm and have never missed it by more than 2 hours. I very rarely have unprotected sex. Should I be getting my period or is it normal that I am not?
