I recently decided to change my pack start dates, to a later date. I was instructed that the safest way to do that was to skip my sugar pills and begin my pack during that week. I ended my 21 days on a wed took one sugar pill thurs n began my new pack friday. I didn't get my period as usual that sunday but instead come tues afternoon I began some light bleeding and have been lightly-moderately bleeding ever since. Its been over a week now and I'm getting a bit worried as I will be soon starting on week 3 of my pack and expect my period week 4. Is this normal or should I schedule a visit to the Dr.?
