Does having implantation bleeding means pregnant?

Not necessarily. Implantation bleeding is a common early sign of pregnancy, but it is not a definitive sign. It occurs when the fertilised egg implants itself into the lining of the uterus, which can cause some light bleeding or spotting. However, implantation bleeding can also be caused by other conditions, such as hormonal imbalances or certain medications. It is important to talk to a doctor to confirm if you are pregnant or not.
