Hi. I am 38 years old and a mother of two. I have been using the Nuvaring for about 7 years. Unfortunately the pharmacy had the Rx on backorder. Dr said not to insert it after the 3 days of insertion had passed. I was told to wait for my next menstrual cycle and then insert it. Unfortunately, that last menstrual cycle never came and I did not have sexual intercourse that month. Every urine test and blood test have come back negative, but my lower back is killing me and suffer from a lot of cramps. Clothes are starting to feel tight on me and my stomach is getting bigger. If anyone has felt like this, I would appreciate to hear all feedbacks.
