"i&#039;m 31 with two kids and i always had regular periods.  i was on the pill for many years and decided to try the depo shot.  i had some spotting but my period completely stopped after the 2nd shot.  it was very nice not having a period and taking a pill every day.  i didn&#039;t start gaining weight until the 2nd shot, and i felt hungry all the time!  i&#039;ve always been a small person and maintained my weight without diet even having 2 kids.  i had 3 depo shots total and went back on the pill because my weight kept going up.  i gained 10 lbs and haven&#039;t been able to get rid of it since."
