hi i had gone through your query and understand your concerns. i would come up with two most possibilities to fit your condition of INFERTILITY
1.first possibility is,PCOD; POLYCYSTIC OVARIAN DISEASE
is one of the main factor of infertility in females nowadays. Women with PCOD have High levels of male hormones (androgens),An irregular or no menstrual cycle ,Many small cysts (fluid-filled sacs) in their ovaries (although this may not always be the case).due to above reason the OVUM CANT BE RELEASED
ULTRASOUND SCANNING FOR PELVIS may confirm the diagnosis.
2.second possibility is,HYPOTHYROIDISM;confirm with blood test
for thyroid profile
rule out other possible causes like
and semen analysis
of your husband.
I hope this is helpful for you, thank you
