well I am still on Mirena and I am scared to get off of it. I have 2 kids and i was on depo&pills with both kids... and the Mirena is the only thing that helps but its very painful with all of the side effects.. my body feels like i always have the flu,i get sharp sharp stomach pains all day every day...its hard to tack my 3 yr old outside to play and lift my 1 yr old ........the only reasons i got on Mirena is i cant have another kid is already hard being 20 yrs old wit 2 kids...well what I am saying is what should i do ..what other birth controls could i use that is effective like Mirena but without all the side effects .........a.k.a JADAKISS
