"i switched off my old birth control because insurance didn&#039;t cover it and $80/mo just became too much to handle. my doctor recommended yaz despite the fact my old birth control was completely different hormonally while i didn&#039;t gain any weight on yaz i did feel bloated and retained water for the whole week before my period and then the week of my period as well. i was anxious and short tempered i even became violent towards my husband for absolutely no reason. it wasn&#039;t until this began that i knew i had to change something i couldnt live like this this is not me at all. i couldnt believe how moody i felt and how it felt like my insides were fighting every time anything would happen. i havent given my new birth control enough time but  we&#039;ll see"
