Please do take a UPT card test to rule out pregnancy. Avoid taking oral contraceptives further as it can disrupt your hormonal balance and may result in irregular periods or even infertility in a later stage of life. Also remember, life is very precious. Don't take any chance with life. Emergency Oral Contraceptives can only prevent pregnancy, they cannot prevent STDs including HIV infection. Always insist your partner to use a condom. You may also have a female condom instead.

Hello there. I can understand your concern.  You can wait for a few more days and see. If it doesn't come, take a urine pregnancy test.  But since you have taken the pill, the chances of pregnancy are slim.  Consult a gynaecologist in person for further evaluation and management.
