Hello dear
I understand your concern
First you have to find the cause of irregular period.
Your symptoms could be due to hormonal imbalance, polycystic ovary disease,
endometriosis,
adenomyosis,
thyroid dysfunction.
I would suggest to consult the gynecologist and undergo reproductive and thyroid hormone analysis, USG scan,
ovarian follicle study to confirm the cause.
Specific treatment will depend on the cause.
Drugs like birth control pill and
progesterone pill can be useful to regularize the period.
Once your period become regular, you chance of become pregnant will increase.
Drug like clomiphene citrate and FSH analogue could be useful
Avoid stress, take health diet, drink plenty of water and do regular exercise
Hope this may help you
Contact further for follow up if needed
Best regards
Dr. Sagar
