If it was a normal period, you  got pregnant after the period.  People don't have periods when they are pregnant.  Get an ultrasound if you have not already, and ask the doctor to give you a due date based only on the measurements of the embryo.  Then you can run the due date through an online conception calculator to confirm.  But don't wait -- the later in the pregnancy it is, the less accurate ultrasounds are for confirming conception dates.
