curious

Just curious... the hubby and I BD for the last time on October 20th before he deployed. I had a period (which was a day late) October 30-November 3. It was light most days and normal on the 2nd I think, and spotted on the 3rd until that night when it completely stopped. Just want a little input before I waste money on a pregnancy test and get our hopes up but could I be pregnant? No bashing please.
