Irregular cycle

So about 9 days before my expected cycle (Jan 29th) I had some spotting which lasted for about 4 days. One of those days (the 22nd) there was a little bit heavier spotting which looked more like a darker red so I considered it the start of my period so I logged it. However after changing my tampon a few hours later, it looked more like spotting than an actual cycle. I then had a couple more days of very light spotting and then on my actual period date, nothing. It's been almost a week now and nothing. I even took a pregnancy test which came out negative.

My question is, should I still log on my data that I had my period on the 22nd for just one day or since it was only for a few hours to just delete it and say I have a missed period? *ON a side note, I am going through a little stress with work, wedding planning, and family stuff plus been going to the gym more often so I think the weight fluctuation might also have something to do with my irregular cycle.
