"the 10 is for effectiveness, but for nothing else. generess kept me baby free. i have endometriosis, why my dr prescribed this med, and my cycle is only 2 days but still pretty heavy. but oh the side effects. i&#039;m 21, breaking out worse than i did even going through puberty. my appetite has spiked, i&#039;ve gained about 8 lbs, and can&#039;t seem to get it off with my usual gym/boxing class regimen, i already practice a mostly yeast-free eating lifestyle and still nothing helped. further- my anxiety is off the charts, i have a history with depression but haven&#039;t actually experienced it like this in years- which adds to the constant fatigue. switching to mirena this cycle- i hope your experience is better than mine!!"
