"i have been taking kariva for about 8 months, and so far i love it. my skin has cleared up, i have less cramps and far less moodiness before my period. also, my periods are usually only about 3 days long when they used to be almost a week. i love this birth control! also, i haven&#039;t gotten pregnant yet which is a huge plus. only negative is i have gained about 15 pounds since starting kariva (much of which went straight to my breasts). this weight gain could however be from the stress of college and a new boyfriend. also, the first month i took the pill i would get incredibly nauseous everyday around 8 or 9 pm, but thankfully that subsided. occasionally i will get this way on the first pill of a new pack but it is bearable. overall, love it."
