Dear missjennifer: If one looks at the guidelines about combined oral contraceptives (would apply to the NuvaRing, too) older women can use these hormones if they are non-smokers, have no history of deep vein thromboses, are not diabetic, are not obeses, and have well controlled blood pressure (including those taking medications). Here is a citation from the American Academy of Family Physicians, targeted to health care providers, which summarizes the medical contraindications to NuvaRing use (and other forms of birth control):

http://www.aafp.org/afp/2010/0915/p621.htm l If we do give hormonal birth control to a woman with an elevated blood pressure (on meds or not) we usually have her back in to recheck blood pressure when on, say birth control pills (BCPs). If BCPs seem to make blood pressure worse she is taken off. My best GUESS is that you may not have had severe hypertension, and that the Ring did not worsen your BP.
While there are guidelines, what an individual MD decides they are comfortable with is what they will do. Your experience with the two MDs' response to the same patient is a case in point. I do not know your full history (especially your BP numbers and body weight) but I would suspect that your original MD was still within "standards of good practice". If you went back to your original MD they might renew your NuvaRing prescription.
Again, my best GUESS is that the newer MD wants to try you of DepoProvera rather than the NuvaRing. DepoProvera does not contain any estrogen; it is a higher dose of synthetic progesterone. DepoProvera is designed to eliminate menstrual bleeding but some women can experience erratic breakthrough bleeding.
Every method of birth control has its pluses and minuses. Which ever MD you decide to utilize, be sure to ask lots of questions about the method they suggest. You are asking all the right questions--keep it up.
Yours,
Jane
