I used the Copper T, Paragard, for 5 years after the birth of my first. Insertion was about 7 months after her birth, and my MW said to come when I was on what seemed to be the very end of one of my cycles...It was not painful, and I never felt a thing.
As far as my period, I did not cramp or bleed heavily after insertion, and it made my periods shorter even though it was non-hormonal. I have always had very heavy periods, and it was nice to have the duration shortened. I have recommended it to so many friends because of the no maintenance and no hormones- I have never been on hormonal BC and would never put my own child on it after using an IUD.
And as far as the cost, you can order them directly from Canada if you provider does not have in stock. PP, I saw that you said you went on the hormonal because other was not available, that sucks! A very good friend of mine ordered hers directly and paid the same she would have paid in our MW office, and its the exact same product.
I recommend the Copper T to everyone- I used a Diva cup with it, never had any issues with placement and it worked great- after this pregnancy I will be putting one back in asap!
