"it&#039;s effective in no getting pregnant but my experience has been horrible i have a 7 month old and got this at the postpregnancy checkup ..it was okay at first...then i started to bleed it was light but changed and i as on my period for almost 3 months straight it stopped finally but then would start again very irregular ...it might be regulating but i get my period and it lasts almost a week and half on christmas then gone but came back extremly heavy a couple of days into new years..on top of that i&#039;ve been tired no sex drive and depression. .i get upset and cry and very insecure i get bad mood swings. i hate it. i have a doc appointment th e 23rd jan to see a doc to get it removed or see my options !! but everyone is diff. this is just me"
