Hi
Dr. Purushottam welcomes you to HCM virtual clinic.
I have gone through your query. 
I think I have understood your concern, I will try to suggest you the best possible treatment options.
1) First of all do not panic.
2)To achieve normal and regular cycles I will suggest use of Tablet 
Deviry - 
Medroxy Progesterone Acetate 10 mg daily from day 11 of the cycle for 10 days. Usually menses start 3 to 7 days after finishing the tablets. You can repeat the same for at least 3 cycles. Later on observe for regularization of your cycles.
Please seek prescription support from your treating doctor for the same.
3) Please opt for a healthy diet and regular exercise regime.Include more fruits, salads and vegetables in the diet. Avoid deep fried foods, bakery items and refined sugars. Also, start on Vitamin B 12, 
Folic acid and Omega 3 supplements.
I hope my answer helps you.
Thanks.
Wish you good health.
With regards
Dr Purushottam Neurgaonkar
