"i was asked by dr to try mirena as the pill was causing a skin condition of my vulva to get worse.  i didn&#039;t want to as the progesterone only pill when nursing made me gain weight. but she suggested 3 months so i agreed to prevent my pcos.  it hurt a lot!! i cramped really bad for an hour and bled for a day or two. i then had 2 periods per month.  yes, they were lighter and no pain (it helps with pain my dr said.)  i also had dizzines. i felt like i could faint often! i also was very forgetful. i forgot my son&#039;s ortho appt 2xs and never had in 3 years!!! i hardly ever have acne and did all the time. i have been off a month and that quit, normal period. i lost hair but have lots. it did not hurt coming out my only good comment. ha"
