My doctor prescribed me MonoNessa the other day and I started taking it last night. I wanted to start it as soon as possible, but while I was reading the information pack it comes with it says that you're supposed to start taking either the sunday after your period starts or within the first 24 hours of your period starting. My period ended only about 1 or 2 days before I took the first pill. Even though I didn't start it on my period is it still going to work and prevent pregnancy? Another question I have is, when do I take the inner circle (green) pills? Do I start taking them the day my next period starts or just continue taking the outer circle pills until they're gone and then take the green ones?
