hiii mam,
You are 20yrs now and menarche on 11 yrs. Basically period may be irregular for first 2 yrs after menarche (due to
anovulation) which is quite normal. After that it becomes regular.
Your current problem is irregular period with facial hair. I think you are suffering from "OLIGOMENORRHOEA" due to "PCOD" (Poly Cystic
Ovarian Disease) and THYROID problem. So need to investigate properly.
** OLIGOMENORRHOEA:
It is defined as infrequent period and delay of several months in between and more common in pubertal girls.It is mostly due to inadequate maturation of H-P-O axis and inadequate hormonal stimulation.
The cycle are often anovulatory in first 1-2 yrs.Gradually full development of normal ovulatory cycle and it will not have any harmful effect in future
fertility.
Other Causes:
1)Mental & physical stress like vigorous exercise
2)Anorexia nervosa-if wt less than 47kg,mens remain scanty.
3)Over wt
So you need to do a USG, Thyroid function test, FSH/LH,
Lipid Profile with blood sugar,
Prolactin level to evaluate hormonal imbalance and consult to your gynaecologist.
Along with maintain a healthy diet, Control wt and Regular light exercise.
All the best. For further suggestion mail me.....my Id: soumenmmch@gmail.com
