"this is the best birth control i have been on so far! i used to be on the pill and it made my periods irregular, made me gain a crazy amount of weight, made my acne worsen, made me super emotional all the time, and many other bad side effects. i was off birth control for a couple of months and was back to my normal self and actually lost about 50 pounds. my doctor thought i should take birth control again and recommended that i switch to this, so i took a chance. i had one period after i got my first shot (about 8 months ago) and haven&#039;t had one since. the only bad side effect that i have had with this shot is i gained a little bit of my weight back."
