It is possible that you could be pregnant, as implantation bleeding (light spotting or bleeding) can occur around the time of a missed period. However, it is also possible that the heavy bleeding you are experiencing is simply your regular menstrual period. To determine whether or not you are pregnant, you should take a pregnancy test. If the pregnancy test is positive, it is important to see a healthcare provider to confirm the pregnancy and discuss your options.
