"i am a 21 year old female and i had skyla placed in two weeks ago. the process itself was not comfortable and involved some pain, but afterwards i had a couple hours of slight cramping and then i was fine! i bled for the two days after it was implanted and then it stopped. i just finished a period that lasted three days :). my period prior would last for more than 7 with severe cramping. i&#039;m already loving this."
