"the only painful thing about the insertion was the speculum. i have pcos and was told skyla would be best for thinning my lining. i&#039;ve had it almost a month. i&#039;ve spotted everyday, and there is an increase in vaginal mucus but that&#039;s common when your lining is thinning out. it is taking a while for the string to move up and for to my cervix, but i haven&#039;t discovered anything crazy with this or anything bad. the cramps in the beginning were painful and my period lasted a full 7 days instead of the usual 4-5 days. since getting this i&#039;ve had 2 periods and that&#039;s totally awesome. its regulating me and making it so much easier to track (if you do track your period and ovulation) and if anyone has polycystic ovarian syndrome, i would get this."
