I had a Mirena insterted. This is a Progesterone IUD and lasts 5 years. I've had some spotting with it, but it generally makes it so your periods are negligible. Even lighter than what they were when I was on the pill.

If, at any time, you decide to have another baby you just have it taken out. Pretty good really. I haven't had any pain or anything, but it's probably one of those things you'd want to research before having it.

Mine was inserted at my six week check up with bubs about a month ago.
