You are not VERY fertile whilst on you period but you have as much chance of getting pregnant whilst on your period as any other day in the month ,woman ovulate on different days ,The average day a woman ovulates is day 14 from the first day of your cycle, but average isnt everybody so it is possible your pregnant if you havent allready you can take a test now and it should be accurate good luck
