What happens if I get pregnant while I still have the progesterone IUD in place?

Depends on LMP. We usually recommend removal. While removal might cause you to lose the pregnancy, leaving the IUD increases the risk for severe intrauterine infection. As well, the progesterone, like depo-provera or norplant, (levonorgestrel) might increase the risk of a tubal pregnancy, therefore an ultrasound to determine where the pregnancy resides is as important as removal of the iud.
