I have reviewed your query and here is my advice. You should go for investigations to know about the basic cause of irregular periods. It is mostly due to hormonal imbalance and the treatment depends on the type of imbalance. It could be due to ovarian/thyroid problem/pituitary gland abnormality. USG or hormonal assay helps in understanding.Sometimes ovulation stimulation can be done and conception can be planned, or test tube baby can be tried. Still in those cases knowledge of basic problem helps in pregnancy care and normality. In case there is no abnormality noted, the menstrual regularity can be attained by 3 cyclical courses of hormonal treatment. Here ovulation is judged by LH surge test followed by unprotected sex from the day of positive test for 5 days at a stretch. You should consult a gynecologist for all needful advice, investigations, and management. Please don't worry. Any health problem has a solution in this era of modern medicine. You would definitely have a healthy baby in your lap! Hope I have answered your query. Let me know if I can assist you further. </s>
