My OBGYN has recently perscribed me Kariva, and after reading all of the complaints about it, it makes me nervous to take it. I'm 19 and I've never taken birth control before. Im wondering if I should even start to take it. I have thick hair which I love, and I'm only 115lbs which I love. I don't want those things to go away. lol. Is there anyone thats had a good experience with Kariva?
