"i got mirena put in about two months ago. insertion sort of hurt, not terribly, but it did hurt.  but, it only takes a few minutes so it wasn&#039;t a big deal. the first two or three weeks were very &quot;crampy&quot; for me. they say this happens more with women who have not ever had children (that&#039;s me).  but, the crampy feeling went away.  now, i don&#039;t feel a thing and it&#039;s all good.  i&#039;ve only had it in a short time and have had two periods extremely light, like i need about four-five tampons for the whole period and even a liner would probably be sufficient. i have lost a couple of pounds since having the mirena, not sure if there is a correlation or not.  the only downside is i have noticed an increase in pimples."
