If you are having sex regularly with your girlfriend and she is not on any birth control protection then delay in her periods can be due to pregnancy. But delay in periods and some other so called signs of pregnancy are not reliable because many other conditions can also cause same symptoms including delay in periods.
I can only suggest to take a pregnancy test either in urine or blood to clear all confusion and anxiety. Because conditions will be quite stressful for both of you until she starts her periods or her test become negative. So, get pregnancy test.
