"I hate this birth control. I was originally taking Gianvi which I absolutely loved because I didn&#039;t gain ANY weight. My acne cleared up and I stayed slim. For some reason my pharmacy switched me to Nikki and in 2 months I went from 121 to 143. I am 5&#039;4 and I lift weights 5 days a week. I use to be defined/toned and now I&#039;m so bloated all the time I look fluffy and bulky. I do NOT like this birth control and my skin does not like it either!! :("
