Light spotting the DAY before period was due?!

Or at least I think it was due that day. Sometimes my periods are irregular but last month it was from April 2-10th. And I had this on the day before it started last month. But since my periods are weird I’m not trying to get my hopes up. But it’s been about 2 weeks since I had this and no period yet. Should I take a test yet or just wait the rest of the month and see if af ever comes since it’s irregular but always comes sometime each month...
