I am 37 years old and I have not been sexually active for a year now. For two months in a row I had periods that lasted 9 days. They weren't heavy and I didn't experience clotting or anything like that, they were just longer than normal. This month I am late for my period and yesterday evening when I went to the bathroom there was some light bleeding but still no period. I am having bloating and lower back pain and mood swings and swelling of my breasts and cramping and I feel like it wants to start, it just isn't. Could this be a sign that I am in perimenopause or something more serious like cervical cancer. Any information that you can give me would be greatly appreciated.
