Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
You are right in judging that increased weight can be on of the factors that can affect reproductive hormone system.
Please opt for a healthy diet and regular exercise regimen.
Include more portions of fruits and vegetables and salads in daily diet.
Avoid refined sugars and deep fried foods and bakery products in the diet.
Please check height for weight,
body mass index should be around 23.
To know about the ovarian status, FSH LH AMH and
prolactin levels should be done on day 2 of the cycle.
Post menstrual HSGHysterosalpingography, will be of help to know about the patency of the Fallopian tubes.
I hope this answer helps you.
Thanks.
