Hello dear I understand your concern Your delayed period is not due to the pregnancy as you had period in previous two months. Causes of irregular period may be hormonal imbalance, PCOS, endometriosis, thyroid abnormality, excessive stress and change in dietary habit. Your period will come in next 3-4 days. If it will not come then consult the gynecologist and undergo following investigations: reproductive nad thyroid hormone analysis, USG scan, ovarian follicle study. Period can be induced by giving progesterone tablet for 4-5 days under the advise of gynecologist. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
