It is not common to have regular periods while being pregnant, but some women may experience light bleeding or spotting during early pregnancy. This is known as implantation bleeding and occurs when the fertilized egg attaches itself to the uterine lining. It is usually lighter and shorter in duration compared to a regular period. However, if you are concerned about the bleeding or experiencing any other symptoms such as severe pain or heavy bleeding, it is important to consult your healthcare provider for further evaluation. They can provide you with personalized advice and guidance based on your specific situation.
