Hi, Thanks for using healthcare magic. I have gone through your available history. It may take 5-7 days after last dose of the pill but it may vary from individual to individual. If you had unprotected intercourse, you should check for the pregnancy. You may consult gynecologist for expert examination and advise. Stress is known to delay menses. So you should consult psychiatrist for detailed evaluation and management. Doctor may advise you to take anti depressant drugs like sertraline or escitalopram or amy offer counselling. Stress management and relaxation exercise like breathing exercise may be of good help. Thanks.
