I started taking yasmin last august--continuously for 4 or 5 months because that was recommended to me for very bad cramps and vomiting during my period. towards the end of september i began having chronic diarrhea, which continues to this present day (february 11th). in january and february i gave myself a break on the pillpack in order to have a period and see if my diarrhea would stop. i've been to a specialist several times about my intestinal problems--i had a colonoscopy and an upper G.I. examination. everything was normal, so i'm beginning to wonder if it's just a side effect of yasmin. i've told every single doctor that i'm taking yasmin, and nobody seems to think it could be giving me chronic diarrhea. i'm quitting the pills this month, but i'm afraid of my severe cramps. does anybody recommend the IUD called Mirena? i'm trying to consider other options...
