Hi Lauren. I don't even use tampons so I don't think the nuvaring would be a good option for me. Pregnancy prevention is not really a concern, but rather it's the pain and vomitting every month when my period comes. I like your recommendation of seeing a hormone specialist. I'm a picky eater so gas probably attributes to my upset stomach as well. What is the generic form of Yaz that you're taking? And did you gain weight while on the pill? I'm just over 100 pounds myself and would consider it a plus if I gain weight from using a birth control pill (including breast growth). I'll contact a hormone specialist since good health is a priority. Thanks so much and I'll let you know how things go after my doctor visit.
