I'm not really a doctor expert but i think it all depends on the guys sperm count but first did you use a condom?? orwhen you ovulate, it could be such that when you had sex first you weren't ovuklating but whenyou had sex the second time you were ovulating. just go see a doctor ok. wish you all the best.
