I have currently been takin levora birth control for 2 years and my birth control pills have not come in the mail. I usually start taking my first active piil on a Sunday, but since I haven't recieved my pills I have missed my first 4 pills of the birth control. Do I take all the pills I missed to catch up or do I just start over on the day I recieve the pills and just take one per day? Will that mess up my period?
