Thanks for your query.
I read your query and I understand your concerns.
Your doctor is right please get the egg release tested by follicular growth scan. Have intercourse from the day eggs are about to release. You have a good chance of getting pregnancy
This method is not 100 % sure. You have to try few more cycles in the same way. You will get pregnant.
I hope I answered your query. I will be available for any followup queries you have.
