I'm a 29 years old woman with pcod and regularly taking dronis 30 for 6 months. My periods are regular since then i.e I get my periods in that 7 days when i'm not on pills but the flow is very less. My question is that if I miss any period even on contraceptive pills, is it considered to be normal and from when should I start the pills if I don't get periods in the 7 treatment free days? My doctor advised to start the pills from the 2nd day of cycle.
