When should I test?

I’ve had the weirdest of periods, I started spotting meat or Tuesday of last week and I thought okay the normal AF is on her way. According to glow my estimated date to start would have been Friday. Friday came and gone with nothing other then the spotting that had been going on and the same for Saturday. I started what I thought was AF early Sunday morning, that stayed around til mid-morning in Monday nothing since then just a couple of spots yesterday and today. Also decided to take a pregnancy test yesterday morning and it came out negative. After doing so research I figured out it was probably to early. So when would y’all suggest I test again?
