Hii dr,I have been trying to conceive for about a year and 4months but unable to do so due to my irregular menstruation(I guess)my dr induced me with progesterone injection before I can menstruate, I have been going to see gynecologist ,he told me to do some tests which I did, I did HSG,there was no blockage,and some other tests, he gave me clomid but it does not work for me,later I was told to do folliculometry ,I did it and I was told I do produce eggs but I don t ovulate.for some months now,I have been seeing my mentruation without taking injection but it was drops and light in brownish colour, my questions are: what could have causes my irregular cycle ?what drugs can I take to regularise it? Can I take premolut N to correct my menstrual cycle?
