This study aims to demonstrate that the expulsion rate is increased but acceptable when inserting Mirena IUDs immediately postpartum, termed 'postplacental IUD insertion'. The investigators will compare the postplacental insertion expulsion rate estimate with rates reported in the literature for 6 week postpartum insertion, which is currently the American standard for IUD insertion postpartum. Secondary outcomes will also be examined; endometritis, uterine perforation, continuation and pregnancy among others.

Intervention Details:
    Device: Levonorgestrel Intrauterine Device
    levonorgestrel intrauterine device insertion within ten minutes of placental delivery using a ring forceps insertion protocol
    Other Name: Mirena
Detailed Description:

The average expulsion rate for 6 week postpartum IUD insertion is approximately 10-12% with a range between 3-20% at 1 year. An acceptable expulsion rate for postplacental insertion (PPI) has not been defined and varies between studies. There are limited data on the expulsion rates of levonorgestrel intrauterine systems. Expulsion rates range widely from 1-3% to as high as 30-40% depending on the IUD and the study. Studies report an average rate of expulsion in ranges approximating 10-12%, similar to 6 week insertion rates.

There are many limitations to published studies including the use of older model IUDs no longer in use, multiple insertion techniques that have been deemed ineffective in reducing expulsion rates as well as varying follow up times making comparison of expulsion rates difficult.
