You've had a period so more than likely no

It's unlikely but not impossible. If you miss your next period, take a pregnancy test. And if you're not ready for a child yet, please use protection. Good luck.

It's unlikely that you would have been ovulating very close to your period coming and so that would greatly reduce the chances of being pregnant. However, whenever you have unprotected sex you run the risk of getting pregnant although personally it sounds as though you just had a strange period.
