I'm getting mine removed Monday! Have you taken a pregnancy test? The bleeding might have been your period. If its negative you need to consult your doctor if you don't get your period in 6 weeks
Did you have the Mirena IUD or the Paraguard? Mirena uses hormones for the birth control and the Paraguard is made of copper and is hormone-free.
If you had the Mirena, it is very common to have bleeding after the removal for a few days and then it may take another few weeks for your body to re-adjust to the hormonal change.
Are you concerned that you may be pregnant?
