"i got my iud inserted jan 4 2016, i am 25 and have no children. the implantation was painful but lasted less than 1 min. i did not experience cramping but i do have spotting. i am currently on my 1st period since getting skyla implanted. i&#039;m used to the pretty much non existent periods from my oral contraception. i&#039;m 6 days into my period :( .  not having to take a pill everyday at the same time and filling a prescription is a plus but i&#039;m so over irregular bleeding. i will give this thing a full 6 months before i consider removing it."
