inserting an intrauterine device
after child birth is usually done around 6-8 weeks after birth.
Because the uterus
is back down to it`s normal size then.
The doctors won`t insert it directly after birth - as the uterus still has to shrink back down to the normal size and any intrauterine device wouldn`t be " held" by the uterus.
Most women won`t have sex during those 6-8 weeks - as you are still postpartum - having postpartum discharge which is first red and slowly turns a different color until it stops after about 6-8 weeks.
You can usually talk to the doctor at your postnatal check up - or just after the birth so that the insertion can be organised for you ahead of time.
Hope this has helped.
