"iv&#039;e had skyla for 2 years. i got it put in after the pill failed and my second baby was born. insertion was a little painful but tolerable. i cramped and spotted after which is normal. my periods were irregular at first but my body adjusted and became regular periods. i get extra sensitive i guess during obvulation and periods as to the cramping and head and backaches. sensitive breasts. after a year when it was nice and convenient as my periods got lighter. my cervical fluid has thickened for sure and after 2 years of insertion i&#039;ve noticed shorter lighter periods. but my main side effects are vaginal dryness, more headaches and more painful breast and cramps. but no pregnancies for 2 years so it works!"
