untill last week, I have not had a period since November. My periods are very irregular. I was waiting to start my birth control until I had my period. Unfortunately, I was not able to get the pills until yesterday. My doctor prescribed aviane, and told me to go ahead and start taking the pills. What my question is, is that do I just take one pill today. Or do I double up on the pills until the days are caught up. If you could help me out, it would be greatly appreciated. Thanks so much and have a wonderful day.
