"this is my second month on skyla, i had the mirena iud before and the depo provera in between. they are all extremely effective. i had the skyla inserted the day i was due for my depo provera shot, i was not on my period ( i thought i needed to be, gyno said no)  the insertion was quite painful!! i tore into my arm with my nails trying to take the pain away from the insertion. i didn&#039;t remember it being that painful with the mirena. i started my period 2 weeks after insertion, cramps weren&#039;t too bad, seemed to be normal and the period lasted a normal 6-7 days. the next month.. i am having contraction like cramps and have not stopped bleeding.. the cramps are horrendous and i am considering having it removed!  not recommending!"
