"i&#039;ve been on chateal for about 2 months now. i have read about the negative side effects of this birth control, but different bodies have different reactions, and so far it has worked really well for me. i have high levels of androgens which gave me really irregular periods so i need to use birth control with more estrogen. i&#039;ve used a different brand before and suffered severe mood swings and night sweats which scared me from using pills for a long time. ever since i gave chateal a try, i&#039;ve noticed that my old reactions to birth control is no longer there. i haven&#039;t agained weight or gotten mood swings. the only negative effect i get is the occasional headache. it works at preventing pregnancy and period regulation for me."
