Has anyone experienced period-like bleeding in early pregnancy that still ended up okay?

Sorry if I'm doing this wrong, but I wanted to give a little more information about my situation. My husband and I started TTC last month. I usually have very regular periods, mild clotting, heavy flow, lasting around 5 or 6 days. I usually feel heaviness in my lower region along with cramping with a 'normal' period. This month I had a 'period' that was started on time not as heavy as usual, no feeling of heaviness, cramps, or clots. I'd say it's more than spotting but not nearly as much as 'normal'. And it's day 2 and it seems as though it might be going away soon. I don't want to test too early in case of false negatives so I wanted to wait a week or so and see what happens. I had bleeding in my first pregnancy, but it was after I knew I was pregnant, and I don't remember it being as much. That pregnancy ended successfully :) Has anyone else had this happen? Does this sound like just an irregular period or am I pregnant?
