So my period has always been super regular (always arriving on Tuesday or Wednesday of that week). But last month it came a couple days early (Sunday). I was expecting my period to arrive yesterday because that would be a regular 28 day cycle. However it didn't come. I spotted a little but hardly enough to wear a pantyliner. Today is the same, hardly enough to wear a pantyliner.

Should I consider that late and test or should I wait another few days to test just in case I get my period?
