I got my Mirena about a year ago after having my first child.
I am one of those women who bled for 7 months straight. It didn't affect my sex life at all. I wasn't going to wait it out because it had already been 6 over 6 weeks since we had sex.
Now that the bleeding has stopped, I love Mirena. It just took a while for my body to adjust.
They have to insert it while you are on your period, which is a little uncomfortable.
I don't have periods at all anymore, just a little spot every month, just at one time of day.
I would recommend that you try Mirena. If you are on Medicaid, it pays for it, otherwise (my doctor told me) Mirena costs about $600-700. It lasts for 5 years, which is great too. And, if you don't like it, you can always have it removed. But I think if you try it, you will like it better than Implanon.
