"i had skyla inserted about a week and a half ago. i also took a plan b pill after insertion. the initial insertion was uncomfortable but not painful. just felt like a little sting. my doctor did not explain to me any side effects and when i left the office i got super dizzy and had terrible cramps that lasted about 3 days. the next week i got my period and the night before i actually started to bleed i had the most terrible cramps of my life (or so i thought). i&#039;m pretty sure the plan b messed up my normal cycle because my period came a week early. 

 

i have had my period for about 4 days now and similarly to others comments it is very light. not messy. but the cramps and back pain are almost unbearable. :(. has anyone else experienced this"
