I have gone through your question. I would advise doing investigation of your partner if not done. And histosalpingography HSG for you to rule out tubal blockages. If both reports are normal then continue these treatments for 3 cycles at least. If not get success then consult your gynecologist and take hisher advice for further management. Hope I answered your question. Would be happy to help you further. Take care.
