"it was very effective &amp; i didn&#039;t experience any weight gain (i lost weight). my periods were short/light &amp; it was nice not having to remember to take the pill everyday. i did experience more pms (also known as random crying), tiredness, dizziness, and light bleeding between periods. i heard your body starts to adjust to these symptoms after a while though, but i got too nervous about not getting my period every month, so i switched back to the pill. if you&#039;re on the fence, remember, every person is different, so why not give it try? it&#039;s only for 3 months at a time. you can always switch back to normal birth control if you have any issues."
