I took my period back to back last month because I didn't want a period. Now I want to shift my period starting day. I stop taking my pill thursday and normally start the following friday. I get my period saturday night. I want to change my period to a week day. I want to still be protected so I dont think stopping the pill today and binning the last two would be a good idea. Can I start the new pack and take them until Sunday, so from monday to the following monday I get my period? Thanks.
