What are the probability of getting pregant after switching from the Ortho patch to the pill?

I had be on the patch for a number of years and I only recently changed spinal column to the pill because my new Dr. refuse to perscribe the patch and I am just wondering the likelihood of getting pregnat right nowWhat are the probability of getting pregant after switching from the Ortho patch to the pill?
I WOULD JUST BE CAREFUL THE FIRST MONTH, USE A BACK UP METHOD LIKE CONDOMS UNTIL THE PILL GETS IN YOUR SYSTEM, THEN IT SHOULD BE FINE!!
YOUR BODY HAS TO RE-ADJUST
I JUST SWITCHED BC'S TOO SO THATS MY ADVICE!
If you used both methods correctly, you shouldn't be at any more risk than usual. If you perceive uncomfortable though, you can other use condoms as well.
Did your doctor explain why he refuse to perscribe the patch? If it is something you were comfortable beside and would like to step back to, you might want to try a clean doctor.
there shouldnt be any problem as long as you use both correctly in a minute if you start to mess up with them later there might be consequences,,,,,give somebody a lift care!
