I had the mirena for 3 years before I had my son and never had an issue. And I just got the copper iud today and it's fine just make sure you have some motrin
I am getting it again next week. I just look at it like it was meant to be. Just make sure you get the strings cut short. If they are too long sex can pull it out. That's what happened with mine
I had an IUD for 15 months, one day I was getting strange cramps. I made a doctors appointment a week later and turned out I was 4 weeks pregnant. I got it removed, it had moved from where it should have been. Had a healthy happy baby girl 3 weeks ago
