I am 19 years old and no longer get periods. My menstrual cycle has never been regular. When it was "consistent" 6 or 7 years ago, it came every 6ish weeks (heavy flow, very painful, and lasted a full 2-3 weeks) but would never cycle more than half a year.
3 or 4 years ago, the extreme periods stopped. I have had 1 or 2 in the timespan. I shrugged it off the whole time because the lack of a period was easier to deal with than having one. I blamed my depression and extreme stress for the irregularity. Recently, I started to wonder if it was doing harm to my body. The stress and mental illnesses are factors, of course, but it's taking a toll on my long term goals.
-I don't exercise (I have no energy, I am EXTREMELY tired 24/7!)
-I am not sexually active and never have been (I have never had a sex drive. I feel this is also a symptom)
-No illegal drug use
-No unhealthy eating habits
-Never used birth control
-No weight gain/loss
I am scheduling an appointment with an OBGYN soon, but I would like to have some knowledge beforehand as to any guesses of what the problems are.
