Mirena

So I had the mirena for the whole 5 years, had went back to the doctor to get it replaced. Had the new one for about 5-6 months when I had to have it removed due to ovarian cysts rupturing. Now I have no birth control and my and my fiancé do not use a condom. I’d have to say 90-95% of the time he has pulled out. I am going on now, almost a year and a half with no birth control and haven’t been getting pregnant. Now I am kinda nervous, yet excited knowing maybe I might be! Like I said we aren’t preventing, but we are not trying either.

Has anyone else used mirena that has had trouble getting pregnant?
