text: you don't want to go with the shot, norplant, iud, if you want to get pregnant sooner, than later.  I'm 32, and I use the ring and I love it!  What is the reason for changing your birthcontrol?  If you smoke, it'll be of concern after age 35, though you should still quit if you do.  If it was because you got pregnant on the last one, you should definitely reconsider that type.  If it's simply because your doctor thinks you've been on it too long, but it works, and you're comfortable with it, get a different doctor.  Birth control changes take time to adjust to, and shouldn't be done for no reason.
