"i&#039;m 15 years old. i&#039;m a sophomore in high school. i started taking the depo-provera shot around my freshman year. it actually hasn&#039;t given me any bad side effects beside loss of hair, i haven&#039;t lost a lot a hair, and mood swings. my freshman year i weighed 155 and now i weigh 119. i&#039;m 5&#039;3 and haven&#039;t gained a pound from this shot yet. i hate shots but it&#039;s definitely worth taking for having no period. i haven&#039;t experienced depression or any of the other side effects except the ones listed above. but not everyone is the same. i would recommend talking to your doctor about it before jumping into taking it!"
