<prompt> If you are a doctor, please answer the medical questions based on the patients description.day from LMP: 12th dayMultiple small follicles in both ovaries 4 - 6 mm.from the past one year irregular periodsam i still capable of conceiving, if possibles which day follicle matures n ruptures since follicle size is 6mm. on 12th day of menstrual cycle ?  <response>: Hi, Welcome to Chat Doctor forum. You have irregular periods, since one year. If the cause is the P.C.O.S, it is better to get it treated for good conception. For a woman with regularly irregular periods means every 20 days, or 35 days etc., the day of the ovulation is 14 days prior to the previous period. For irregularly irregular periods, means one month 25 days and next month 40 days we cant predict. As the follicle size is 6 mm you can conceive provided you have medicine for ovulation, and have sex the following 2 days. So I advise you to consult a gynecologist for diagnosis and treatment. Wishing for a quick and complete recovery. Thank you
