Thanks for the query.
Before you start any treatment i recommend you to reduce your weight atleast by 5%.
This itself will increase your chances of pregnancy
There is nothing to worry about since you are only 26 years old and all other pathologies are ruled out.
Start folic acid
tablets. Eat balanced diet and be stress
This acts as a positive factor in your chances of conception.
You can write to me for further clarification to following link:
wish you good luck,
