ve heard people have had good results from the ortho
evra patch and from the nuva ring, I personally had a couple years of effective
use of the depo shot, but don't know how any of those would affect breastmilk supply. The mini arm implants seem to be a more frequently chosen option these days - they have a high success rate, too.
This is an important conversation for you to have with your doctor or midwife. They can help talk through all your options.
