I am 31 yrs. old and this is month 4 on the NuvaRing. I have been on several different types of BC over the years the side effects had been so severe I decided to give up on BC all together. When my doctor recommended NuvaRing I was leary, but I tried it anyway and was quite pleased until recently. I am not experiencing head aches, nausea, or irregular periods, but I am experiencing problems with my moods. Most of the time I am sad or I get agitated very quickly for no reason. I was shocked to read about some of you experiencing loss of energy. I thought I was going crazy. I don't seem to have any energy...I am tired all the time. I have been taking vitamins, but they don't seem to be boosting my energy any. I have gained weight in my stomach and seem to be gasy and bloated. My jeans are so tight...It is depressing! In a matter of 2 weeks my breasts have grown in size...I am sure I have gone from a 36 C to a D! What I am most concerned about is the blisters that appeared about 2 1/2 weeks ago on the exterior of my vagina. They are very painful and over the counter creams are not working. I am not sure if this is due to the NuvaRing. I have my anual checkup with my OBGYNE tomorrow. I plan on getting all of my questions and concerns addressed. My delima is do I stay on NuvaRing...I like that I don't have to worry about popping any pills and I don't get any major side effects. What should I do?
