Hi,
Yes you need to investigate yourself. Get your hormonal profile done. Serum T3, T4 and
TSH levels. Serum
FSH ,
LH and if you milk like discharge from nipples then
prolactin levels. And Along with this you will require Your ultrasonography and
Complete blood count and Urine routine examinations done. This should help you. If everything is normal, then you need to take progesterone pills cyclically for 10 or 21 days in every cycle.
These will be prescribed by your gynaecologist.
