This is hard to say why the doctor changed you that is really a question for the doctor both of these are very effective birth control which one seems the best for you sometimes they may change because of break thru bleeding or early bleeding etc its kind of strange to have the doctor just up and change it unless you were having problems..Just call the office and let them know what you feel and ask why they changed it.Or it may have been a different doctor some favor one over the other for whatever reason but you are the patient and yu have the right to ask these question and more so if you perfer one over the other wish i could be of more help but your answer is at the doctors good luck... Happy New Year

There are somewhere around 200 birth control pills and the major differences are the manufacturers. There are lo dose ones and progesterone only ones, but the major ones used are both progesterone and estrogen, and the doses of each may vary a little but they do the same thing with much the same effect. Ovral was one of the few pills available when I was on the pill, 40 yrs ago, so they've had lots of practice. All you do to chance is when its time to start a new pack you start that pack.
