I have gone through your question. You have been treated with endometriosis in past and now having irregular periods. So I would suggest 3 investigations for you.1 hormonal study, ovulation profile, thyroid profile2 histosalpingography These reports help in find where the problem is. Then consult gynecologist with these reports and heshe will advise you further. Hope I answered your question. Would be happy to help you further. Take care.
