Delayed period

Angela

So, I took contraceptive pills for 2 months to correct my pcos and my period is due on the 26th but it hasn't come until now. I've had abdominal cramps, gasseous stomach and mild breast tenderness a week prior to the date that my period should come. I am afraid to take pregnancy test because i am nervous it will be again negative.

What do you think? Do I have a chance of being pregnant at this stage?
