Don't do that.
You need to take your pills as directed or just completely skip the placebo week, which is still very safe and definetly a better idea.
You may not get your bleeding, and you should just start a new pack now. Throw out the remaining two weeks from that old pack (you can't just take two weeks of pills). It's also possible that you will spot during your active pills for awhile.
Get back on track with how you SHOULD be taking your pills. Changing when you get your period takes practice and its not something you can just up and move around and have whenever.
