IUD pregnancy or complications


Has anyone ever gotta pregnant with the IUD? Did you always have normal periods while on the Mirena?? Any troubles?

I am currently on the IUD, I’ve had it for about 4 1/2yrs. I’ve always had my period as usual but I didn’t have one last month and I’m at my usual time to have it this month and I haven’t started yet. I won’t consider it late yet until we reach day 18 then I will probably get worried. But just thought I wanted to get to know everyone’s experience with it. Thanks!
