Can you still be pregnant even if you get your period?

Early pregnancy: Some people will have bleeding at the time of the missed period, though it is usually lighter than usual. This is implantation bleeding which can occur when the embryo is growing into the lining of the uterus. However it can also be a sign of a miscarriage. Getting a blood pregnancy test and repeating it in 3 days to make sure it is still rising will let you know if everything is ok.
