Period

Normally my cycles are pretty regular. These last two cycles have been late. The first time it was a week late and my stomach was upset a lot and I was very emotional, then my period finally decided to show up, lasting the seven normal days that it typical does. My current period decided to be five days late, although while being late I still had the cramping , and then it showed up and I only have bled for two days and had nothing on one day and today only having blood when I wipe, and it’s a different color then the typical period can be. Just wondering if I should be alarmed by it or just watch to see what my next period does. Should I take a pregnancy test? I’m not on bc and my bf and I don’t take any precautions, haven’t for the last year
