"i have been using this pill for 1 week now, this is my first birth control pill i have used. i am 15 and mainly wanted it for my acne and i had really really bad cramps and heavy periods. my obgyn told me to start it on the day i started my period so i did that. the first day my head felt cloudy, and i felt as if i was high. when i woke up the next morning i had to run to the bathroom and threw up, mainly just dry heaves. i normally bloat when i&#039;m on my period but i seem bigger than usual and my breast are extremely tender. but other people said it decreased there sex drive but i feel like it has done the complete opposite for me. my periods normally last for 8 days and i&#039;m on my 4th right now with little to no bleeding."
