"i don&#039;t see what everyone is complaining about. blisovi was the first birth control i was prescribed at age 17 and have been on it for nearly 2 years. you just need to give your body time to adjust to the pill! my periods were irregular for about 3 months and now i know exactly when they are coming and how long they will last. only side effects i have are achy breasts a week or so before my period and i feel sick if i don&#039;t have a snack before i take it. overall i am very happy with blisovi."
