I have been on the Nuva ring for almost a year now and just recently started feeling a fluttering feeling in my lower right abdomen which feels exactly like both of my daughters (4 years and 2 years) did when they were inside me. I told my Husband about what I was feeling and made him feel my stomach. He felt two movements. I have not missed a period and they have all come at the same time and last the same amount of time. I am not having any abnormal bowel movements. In fact I thought if I had a bowel movement the fluttering would go away, it has not. I took a pregnancy test last night and it showed negative.
