I have been on mirena for about 10 months now and found out last night that I'm pregnant. I was late on getting my period and got two positive tests and then have spent all day at the doctors office getting a blood test and waiting for the results. Still pregnant and had to get the iud removed. Having to go in for blood tests all week next week. Just thought everyone should know, if something feels off it never hurts to take a test and catch it early. Praying everything goes well with this pregnancy
