Hello dear I understand your concern Your delayed period could be due to hormonal imbalance, pregnancy. If you had sex during fertile phase of period then high chance of pregnancy as you got off your birth control pill. Period couples of day could be due to withdrawal of birth control pill. I would suggest to go for urine pregnancy test and or blood HCG test to confirm pregnancy. If pregnancy test will negative then no chance of pregnancy. In absence of pregnancy, period can be induced by progesterone pill by consulting gynecologist. Avoid stress, take healthy diet, drink plenty of water, do regualr stretching and relaxation exercise Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
