hii Aishwarya,
Very good morning,
Your period was regular before marriage and after that delaying by 3 months. Yon not take any pill and try to conceive.
If you get persistent irregular period ,then you may suffer from OLIGOMENORRHOEA and 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)Hypothyroidism
4)PCOD with over wt.
So you need to do a USG,Thyroid function test,FSH/LH and
prolactin level if period is irregular or delaying more than 2 months and consult to your gynaecologist.
Along with maintain a healthy diet,control wt and regular light exercise.
All the best. If you need extra consultation,then contact with me,my id: soumenmmch@gmail.com
