"i&#039;m writing this because as i do more research to try to find a new bc, i realize most people leave bad reviews!  i had been on ocella for almost 10 years when my doc recently told me it&#039;s known to cause blood clots.  until then i had otherwise a good experience with it.  i think the most noticeable things i can remember or slight dryness and a decreased sex drive.  but no emotional turmoil or headaches - which is what i&#039;m facing now.  i miss ocella!"
