You should be able to feel your threads. You should be checking this once a month anyway. But, check to see, if you don't feel threads make a doctors appointment asap. I had the paraguard, for less than 1 month and it fell out of place and got stuck. I had to have it removed. I would also take an HPT to be safe. pregnancy with an iud can be very serious, causing miscarriage and loss of fertility. if pregnancy test is positive, i am sure they will rush you in to the remove the iud. good luck.
