Hi. I m a 45 year old woman and have been having hot flashes off and on for a little while. But in the last 3 weeks, they seem to be coming on everyday. I was getting my period about every 2 weeks for a year but haven t had one since about the 2nd week in October. I m also experiencing an increase in vaginal discharge. I only have one ovary and my husband had a vasectomy about 10 years ago, so pregnancy is highly unlikely. Is this the onset of perimenopause?
