Thanks for your query.
I have read your query & I understand your concerns.
You will get periods soon. If you dont get, your IVF centre will prescribe you pills to get periods. Hence dont worry about it.
Your doctor is right in advicing to stop herbal medicines.
Chance of getting pregnancy
now as you have missed periods is less & unlikely.
There are good chance of you conceiving by IVF. I wish you all the best.
I hope I answered your query. I will be available for any followup queries you have.
