No. You will only bleed for the usual amount of days. The problem is that if you leave the patch off for more than a week, you run the risk of pregnancy. You shouldn't remove the patch early, but if you do, count this as your fourth week and put the new patch on after 7 days.
If you put on a new patch when it's supposed to be your patch-free week, there are no special dangers. You will not be at increased risk for pregnancy. You may miss your period, and you may have unscheduled spotting during the next cycle.
Yes, early removel of the birth control patch may cause an early or late period. Since you weren't using effective birth control, take a pregnancy test if your period is late.
If you put the patch on before your period is due, you may stop your period or you may have irregular bleeding. Remember that you won't be protected against pregnancy until you've used the patch correctly for seven days.
Putting on the patch just before your period is due may lighten, delay, or prevent your period.
If you're using the patch you don't get a period full-stop - just like the combination pill this method of birth control suppresses your cycles to stop ovulation, thus no menstruation. You get a withdrawal bleed due to the drop in synthetic hormones during your week break, thus if you take the patch off early that drop will occur early thus in turn your withdrawal bleed will be a week early too.
When you stop the birth control patch, you will probably have withdrawal bleeding, as you typically have during your patch-free week. After that, if you had regular periods before you started the patch, you'll probably ovulate in two to four weeks, and get your first post-patch period in four to six weeks. You can get pregnant before your first period after stopping the patch. If your periods were irregular before the patch, they're likely to return to that irregular habit after you stop.
Yes, you can expect an unusual period the first one or two times you bleed after stopping the patch. Your subsequent period will probably be more like those you had before you started the patch.
There's no harm in applying the patch a few day too early. If it's your first patch, just use a backup method for seven days.
I started the patch before my period (like two days before) and it kinda messed me up for a little bit. I bled (spotting and period included) for one month. I stayed on the patch for four years and it worked great. Ask your doctor.

You describe a situation that is low risk of pregnancy. Just make sure that you put your next patch on after no more than seven days (one day of the week earlier than last month's first patch).
If you put the birth control patch on before your period comes, you may miss that period; you may also have unscheduled bleeding or spotting. If you have been using the patch regularly, it's possible that it will lighten bleeding so much that you won't see a period. If you think you made a mistake with the patch, and missed a period, take a pregnancy test to make sure.
