"i had the mirena  inserted 4 days ago now, i decided to get the mirena as i have very very painful period cramps and i had recently moved to a new area and getting the pill was a nightmare. the insertion for me was very very painful, the doctor had to dilate my cervix so it made the cramping even worse, the pain was so bad that i was actually sick. however i&#039;m still experiencing bad cramping days later. i won&#039;t say at the moment if i hate it or not as it&#039;s been only a couple of days but i hope the cramping stops soon!"
