I'm pretty sure they can, being it is possible (uncommon) but possible to have a regular normal period the whole 9 months you are pregnant. Most people say that you most definitely can not have a period if you are pregnant but that is a myth. I know several people who were pregnant but yet still got there period every month they were pregnant and it was very normal, not just spotting. So i would assume that yes it is possible to have your "last" period and still be pregnant.I'm pretty sure they can, being it is possible (uncommon) but possible to have a regular normal period the whole 9 months you are pregnant.

Answer You could be, as the last day of your periode you should be very very light or just spotting if that. I'd take a pregnancy test if I were you.
