"i have been taking mononessa for about 6 years now. i have had no undesirable side effects. my periods are always on time, there not heavy at all, and last generally 4 days, sometimes 5. i have experienced no nausea, and no cramps. i have acne, but i had acne as a teenager, and then it went away and came back years later, so i don&#039;t think the birth control is the culprit. i pay nothing out of pocket, and the one time my insurance did get cut off, it was $28 which i did not feel was completely unreasonable. and most importantly, i have not gotten pregnant since being on it."
