Hi there,
I have understood understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) Sorry to hear about your previous
pregnancy loss.
3 ) I will suggest you to get USG done to know Ovarian volume. Sometimes
polycystic ovaries is a common cause of irregular cycles.
Absence of ovulation, is another cause of this irregularities.
As such previous
miscarriage and it's treatment can not cause irregular cycles.
4 ) As you are trying for pregnancy, I will suggest you to start with
Folic acid, Vitamin B 12 and Omega 3 supplements on daily basis at least 3 months before you plan to get pregnant. This helps to prevent many problems during pregnancy and delivery.
I hope this answer helps you. Thanks.
Dr. Purushottam Neurgaonkar.
