Hello there.
I can understand your concern.
I would like to know, how late do you get your periods. Tell the approximate time intervals between your cycles.
You need to get a few tests done like ultrasound of abdomen and pelvis,
thyroid profile.
You need to lose weight also your husband.
Consult a gynaecologist in person so that she can examine you and go with the reports so that she can have a better idea.
Also get a semen analysis of your husband done.
Best regards.
Dr. Anil Kumar Jain.
