So glad I found this site.
My doctor is trying to convince me to having the Mirena fitted as I'm having very heavy periods every 2 weeks that last approx 8 days. I initially said "no", but was still given information regarding Mirena to take home & read. I was beginning to reconsider but after reading through these postings I will be sticking to my guns & will NOT have it fitted.
Thank you for taking time to share your experiences as it has helped me to make a more informed choice.
