"i am 20 years old and had mirena put in 18 months ago after my son was 6 weeks and so far i like it but i do have some negative comments too. the insertion wasn&#039;t bad just had cramping after wards. my boyfriend feels it most of the time when we have sex. my hair loss is pretty bad. i feel like i have 5 lbs i can&#039;t lose. i bled straight through the first month i had it in. then didn&#039;t get my period or spotting for a whole year and now i get a regular period every month. sometimes i do experience some cramping when i bend over a certain way and its sharp and very painful. but all in all i like that i don&#039;t have to take a birth control everyday and i don&#039;t have to worry about any more babies."
