"i&#039;ll be very up front about mirena. i&#039;m 23 years old and a previous cervical cancer survivor. if anyone knows about cervical cancer, you can&#039;t just choose any birth control and i&#039;ve tried everything even nuvaring which may i add got stuck. i&#039;ve always heard horror stories with mirena/iud and since i&#039;ve had my son of one year, i&#039;ve been cautious of what to use. so when i went to my last gyno, 2 miscarriages later, he told me its best if i gave mirena a shot. the insertion was uncomfortable and some cramping throughout the day. i recommend also some pain relievers before you go. no side effects yet, but i love my mirena. i love not worrying and being able to strike up the mood with my husband and have to deal with stubborn condoms. 5 stars"
