I'm on the pill and this week is my placebo pill week, but my period isn't to start until Friday.
So do I still start my new pack next Sunday when I should be? Even if on my period? I was off the pill for a few months so I'm thinking thats why my period is still off a little bit.
Thanks for all responses! :)
