If multiple pregnancy tests have come back negative, you should wait a bit longer and take another test. If you still have concerns, consult a gynecologist for further evaluation. Stress and other factors can also cause irregular periods.

After unprotected intercourse, taking the emergency contraceptive pill (I-pill) can prevent pregnancy by blocking fertilization. Since you took it within 24 hours, it is more effective. Having sex on the last day of your period usually means a lower chance of pregnancy. Pregnancy symptoms typically appear after a few weeks, but missed periods or nausea can also be signs. If you're feeling anxious, consider taking a pregnancy test.

Don’t worry if your Primulot N dose timing was a little off. If you took it every 6 hours rather than 8, you might experience some slight spotting. The reason for this is that your hormone levels change. To solve the problem, take your medicine after every 8 hours as directed. This adjustment will help to normalize your hormone levels and prevent any bleeding. 

Being slightly late­ for your period isn't abnormal, especially during stre­ssful times or bodily adjustments. The unprote­cted sexual encounte­r on February 7th, followed by taking eme­rgency contraception, could impact your cycle. That might e­xplain your delayed period. Re­member, stress, die­t modifications, and illness can also affect menstruation. If you're­ still worried, a home pregnancy te­st can offer clarity. 

You have a small cut on your vagina after you were intimate. This is no surprise because the skin down there is delicate. It might cause pain, redness, or a bit of bleeding. To speed up the healing process, you can keep the area clean and dry, avoid using scented products, and apply a gentle cream or ointment recommended for cuts.
