Missed period with hpt negative.

Hi doctor.Me n my gf made out on december 5th.there was no intercourse. But there was a situation where after i removed my condom i touched my penis WHICH HAD PRE.CUM on it and after 5 mins USING SAME FINGERS I FINGERED HER. I was worried regarding this so waited for her periods which was due on December 26.She gets periods for 4 days and usually delays. Since she did not get her periods, 2 days after missed period we did home pregnancy test and result was negative. So we waited again and then after 5 days we again did the home pregnancy test using velocit home pregnancy kit and result was negative.(7th day of missed period) So again we waited another 5 days and took the home pregnancy test using velocit home pregnancy kit and the RESULT WAS NEGATIVE.(12th day of missed period) Today is 9th jan she still has not got her periods Is she pregnant? Or periods is delayed doctor?
