Could it be implantation bleeding if you have light not like a normal period and has lasted for 3 days how long does last when will pregnancy test work?

Implantation bleeding: may occur when the fertilized egg implants in the lining of the uterus. This bleeding is usually light, shorter in duration, and a different color than menstrual blood. It may be pink, brown, or red. Implantation bleeding typically lasts for a few hours to a few days, but can sometimes last up to a week.

However, it's important to note that implantation bleeding is not a reliable sign of pregnancy, as many women experience similar spotting during their menstrual cycle. To confirm pregnancy, a pregnancy test should be taken.

Pregnancy tests: Work by detecting the presence of the pregnancy hormone, human chorionic gonadotropin (hCG). This hormone is produced by the developing placenta and levels increase rapidly in early pregnancy. Pregnancy tests can be taken as early as 10-14 days after ovulation and become more accurate as pregnancy progresses.

If light bleeding persists or you have any other concerns, it's best to consult with a healthcare provider for an evaluation and proper diagnosis.
