I started taking Kariva this past month and I have been on it for 2.5 weeks. Lately, I have not been feeling myself at all (feeling sadder). I've gotten breakthrough bleeding on Kariva and it has made my breasts grow. I was on Aviane before and switched because I had breakthrough bleeding after 4 months. I've only been on Kariva for two weeks so should I stick it out for another month and see how it goes or switch pills? Thanks!
