It is possible to experience bleeding that resembles a period even if you are pregnant. This is known as implantation bleeding and can occur around the time your regular period is due. However, it is important to note that not all women experience implantation bleeding, so it's best to take a pregnancy test to confirm whether or not you are pregnant. If you continue to experience pregnancy symptoms or have concerns, it's recommended to consult with a healthcare professional for further evaluation and guidance.
