"i have had the mirena in for a year now. i&#039;m 29 and i haven&#039;t had babies. i&#039;ve tried all sorts of birth control pills and nuva-ring. all they ever did was cause depression and mood swings. mirena on the other hand has been a blessing to my uterus. i had slight cramping the first day or two and since then my periods have disappeared, i haven&#039;t had a period in 6 months, no monthly symptoms either. mr. mirena deserves a trophy and a million dollar mansion for his kind help."
