Birth control while breastfeeding

Emily • 22. Married. Have one angel baby (1/19/14) and a baby boy (12/4/14)
What do you use for bc or are planning to use? My dr and I discussed it at my checkup yesterday. I'm breastfeeding only-no formula. She recommended the mini pill with no estrogen. I've been on the regular pill before and I'm just not sure what I want to do. I'll need to decide before my 6 wk checkup. My husband and I want another baby for sure within the next couple years. We don't want to wait say, 5 years. Opinions/advice please.
