Birth Control
"I have mine for about six months now. I am breastfeeding my eight month old baby and so far, no period yet. Or cramping or spotting. 

The insertion was not painful, exactly like a pap smear but I do have 4  kids so that is expected with the uterus stretched out. 

No pregnancy scares so far either.

So far, it is working exactly as it should. Birth control that works with minimal effort."
