Could you be pregnant if after 3 weeks of your last normal period started having on and off brown sometimes pink discharge for 5 nowand also spot sex which im once a?

Yes, it's possible that you could be pregnant. Implantation bleeding, which occurs when the fertilized egg attaches to the uterine wall, can cause light bleeding or spotting that can be brown, pink, or red. However, it is important to note that implantation bleeding typically occurs 6 to 12 days after ovulation and usually only lasts for a few days. Additionally, spotting after sex can be caused by a variety of factors, including cervical irritation or hormonal imbalances, and is not necessarily a sign of pregnancy.

If you had unprotected sex during your fertile window (the 5-day period before ovulation and the day of ovulation itself) and are experiencing unusual bleeding or spotting, it's a good idea to take a pregnancy test. A urine pregnancy test can be taken as early as 14 days after ovulation, while a blood test can be taken as early as 10 days after ovulation. If the pregnancy test is negative and the bleeding continues or becomes heavier, it's important to see a healthcare provider to determine the cause and receive proper medical care.
