I am 47 years old. Had a tubaligation 19 years ago. I have not gotten my period for 21/2 months now. I experienced pms symptoms both months. Last month I experience the symptoms in 2 two different occasions for a week at a time. I only had a little brown discharge as if it was the end of my period. Nothing more up to the present. My breasts are sore right now as was the past two months, slight cramping, leg pain, sleepless nights (insomnia), tirednes during the day even if I get up at 11am. Should I do a pregnancy test or is this normal for perimenopause?
