Hello there, I have had an iud for 3 years, I recently had paragard inserted in december. Paragard iud is copper, no hormones, and few side effects.
I did have mirena, hormonal iud, but I had problems with everyday bleeding on it and wanted to switch.
Paragard can make some womens periods heavier, mine never changed. Paragard can cause worse cramps during periods, mine are crampier, but nothing that advil cannot handle!
Overall it is a very effective and safe method of birth control.
planned parenthood is good at giving women iud's who have never had babies, in case you have not..A lot of regular gyns are not comfy with the idea, but pp does it all the time.
