Seeing light spotting after sex can be alarming, and the question of pregnancy often pops into your head. While implantation bleeding *can* cause light spotting, it's crucial to understand that it's not the only possible reason.
Implantation bleeding typically occurs about 6-12 days after conception, when the fertilized egg attaches to the uterine lining. It's usually very light, often just a few drops of pinkish or brownish blood, and doesn't last long.
However, spotting after intercourse can also be caused by other factors like cervical irritation, polyps, infections, or even just hormonal fluctuations. If you're concerned, track your symptoms carefully – note the color, amount, and duration of the spotting. Taking a pregnancy test after a missed period is the most reliable way to determine if you are pregnant. If the spotting is heavy, painful, or accompanied by other concerning symptoms, consult your doctor to rule out any underlying medical issues. Don't rely solely on spotting as a pregnancy indicator!
