You had your last menstrual cycle on Oct 20Th it lasted till 25Th but was really light an today is Nov 4Th and you experienced pink blood when wiped could this be implanation bleeding?

Implantation bleeding typically occurs 6-12 days after ovulation, which would be around November 4th if you ovulated on October 27th. However, implantation bleeding is typically light and only lasts for a few days. The pink blood you experienced could also be a sign of your period starting early, or it could be caused by other factors such as stress, hormonal changes, or infection.

If you are concerned about the pink blood you experienced, it is best to talk to your doctor for an accurate diagnosis. Your doctor may recommend a pregnancy test or other tests to determine the cause of the bleeding.
