I would say no, as you were about 10 days into your cycle. Ovulation begins about 14 days after the first day of your last period. You would have started your ovulation process around the 27th of Sept. Sperm can live inside of you for a period of time but i would say if your pregnant, odds are your bf is the daddy.
