Thanks for our query.
You seem to have difficulty in ovulation.
For some reason, you do not respond to ovulation inducing agents, and hence fail to form eggs.
Please consult an Infertility
Have assessment of your ovarian reserve
, that is, capacity of ovaries to produce eggs.
THis is best done by a blood test called AMH and by AFC ( antral follicular count ) on day 2 of your periods via ultrasound.
Other reasons could be resistant polycystic ovaries
, premature ovarian failure
