"I had mine for about one month now. I have 4 kids so the insertion was nothing more than a pap smear. There was spotting for about two days but no cramps. I am still breastfeeding my child so I don't expect to get a period till she is one. 



The only downside is that it is uncomfortable during sex. There is some pain either because of the IUD or because of the childbirth and the  breastfeeding making it very dry down there. My husband can only say that it feels awkward. 



I have a follow up appointment in a week and will be asking the doctor about it"
