Basically I take a pill every day for 3 weeks then 1 off for my period. This month I lost a pill, so I took one from next months to make up for it because bluntly I had sex and wanted to be covered. Now I am due to start my next pack tomorrow but I now have one less pill, do I start the new cycle tomorrow or do I wait till Tuesday, or do I finish one day early this month, I am sexually active and would very much like NOT to become a mum anytime soon. Advice please x
