I think it's a great form of birth control. I don't have any experience with the iud, but my doctor & I were looking into before I got pregnant again. Everything he explained to me about it, seemed like a perfect form of birth control. You do have to have atleast one child to use this form though, & it's easier for the doctor to place in your cervix right after you've given birth. I'm honestly not even sure if they'll do it unless you immediately had given birth. The iud is about as effective as any other form of birth control, plus it lasts for 5 years without a run back to the doctor for a re-fill or new shot every month or so. I'm not sure how much it is to get placed, but I do know that it costs $100 to get taken out before your 5 years is up... but atleast you have that option. Good luck!
