"had my mirena inserted about 2 weeks ago. i am 22 and haven&#039;t had any kids, i wanted an alternative to the pill as i&#039;ve been on it for 6 years. i have to say that i was pretty nervous after reading so many bad comments. i was on the 3rd day of my period and for me the insertion hurt like a couple of pinches and a really bad cramp that gave me all hot and made me nauseous. but it only took about 10 minutes and then it was okay. the rest of the day i had fairly strong cramps but nothing unbearable. the next day i felt back to normal. my period lasted another couple of days and stopped like normal. since then i have had very minor spotting with an odd little cramp here and there. very happy so far."
