I had my normal period and 2 weeks later I have light vaginal bleeding. I am not bleeding enough to fill a pad in a day. Sometimes its red, but mostly it's a brownish color. I have slight cramping and back ache off and on and its been going on for 8 days now. I am 44 years old and did not have my first period till I was 16-1/2. Could this be the start of menapause or could it be something else. Should I see a dr??
