Anticipation...

I'm kind of at a lost with my menstrual cycle this month. Although I have recorded the previous dates when I have my period but this month I'm a little bit confused if my period will come or if I have been late or if it's time to check and start doing pregnancy test. I had my period on Sep 5th and the 27th which showed that I had 22 or 23 days cycle. I should be expecting my period for this month 2 days ago the 20th if my cycles are still the same but sometimes it changes from 22, 23, 24 and 26 days before my next period day comes. So, today is supposed to be the 25th day since the first day of my last menstruation. I felt some minor cramps 2 days ago but still I'm not menstruating. Am I pregnant or not? Hmmm, I am tempted to start doing the pregnancy test but I think it's too early to do it and besides I'm scared what might be the result. I don't want to get disappointed again. I guess I need to wait couple of more days. Waiting feels like forever. Wish me luck friends!
