It's normal for your period to be late after unprotected intercourse, as the body sometimes reacts this way. It's common not to show any symptoms for a week. Pregnancy symptoms might appear later. Stress or changes in your routine can also delay your period. If you're concerned, taking a pregnancy test in a couple of weeks can give you a clearer answer.

Looks like you went through a medication abortion. Common side effects include terrible pain bleeding and vomiting. You may have completed the operation if the bleeding is stopping and you no longer feel any cramps after taking the second set of pills.

Blackheads are small bumps that form when hair follicles get blocked by dead skin cells and excess oil. This can happen due to excess sebum, hormonal changes, or improper skin care. To reduce blackheads, use a gentle exfoliating scrub and a non-comedogenic moisturizer. Always clean your skin well to avoid irritation and prevent the urge to squeeze blackheads.
