Are you going to the Willow Women's Clinic on Burrard? that's where I got my copper IUD 4 years ago.

I don't have kids and debated about Mirena, but I was psycho on the pill, and at $300 (at that time, could be more now), I just couldn't chance it. So, the cheaper copper one won out, and I haven't looked back. I did notice that my periods were heavier and cramps were more, but they got back to normal after about 6 months.

I should mention that it wasn't without subsequent trips back to the clinic. Insertion was a bit traumatic as the doctor couldn't get it past my cervix. It eventually did. Then after about 2 months, the strings disappeared. After the ultrasound, it was determined it crept up my uterus. No biggie, they'll just have to go "dig" for it. Thankfully it dropped back down last year.

I was recently at my GP for a pap, and she mentioned that even though most doctors say the copper ones are good for 5 years, the manufacturers only guarantee for 2.5 years. I'm due to get mine out next year and I'll likely get it again.
