"pros: discreet, no pregnancies for 5 years, no daily pill reminders, covered by insurance.
cons: bv like clockwork!  my period remained the same ( 5 days) which could be a pro for some.
 **prior to mirena i was on the pill. after my first child i knew i wanted to go long term birth control. apparently it works but i just can&#039;t deal with the constant bv. when i have intercourse with my husband he can feel the strings inside. if you have a sensitive system like myself, i&#039;d look into other forms of birth control first."
