"i know all the reviews on this are either really good or really bad, but i would like to share my feelings and experience which was kind of in between. as far as effectiveness, it is very effective. i am thankful i have it because i can&#039;t get pregnant since i had a c-section. my periods have stopped, i do not bleed anymore, and even though that is a plus, it does not outweigh the side effects. i have nearly constant fatigue, nausea a lot of the time. i always feel on edge or irritated, sometimes sad for no reason. i get sick a lot more. lots of headaches. the only reason i got this one is because i had limited options since i was breastfeeding and i didn&#039;t want the mirena.
