Spotting or period?

So my period was 3 days late. It's never been late before except when I had a CP in march it was 1day late. This morning around 10am there was a bit of blood when I wiped, and I thought it was my period, so I put on a pad. It's 7.30pm now and there's literally only a few drops on the pad. Usually my first day is the heaviest. AF normally comes in full force with cramps simultaneously. I had some cramps last night but there was no blood. Then when there was a bit at 10am this morning, I had mild cramps but nothing as bad as usual. The blood is mostly pinkish but there was a bit of red at one stage during the day. Now there's almost nothing. Should I test? Or is it just AF?
