Okay lady am on the Mirena birth control I've had it since last November me and my fiancé have been talk a lot about a baby we already have two awsome boys and we're wanting to add one more we're getting married in July 2017. Am wanting to have a baby due in February I like that month a lot it's very special to me. Thought am on BC how long did it take for you to become fertile after having the mirena in.?
