Late, short, light AF... CONFUSED!!!

Sq
Hi ladies! Just hoping for some advice but will try and keep this as short and sweet as possible! I'm usually pretty regular, but this month AF showed 4 days late. When it did, I kept waiting for it to pick up, but it never did, and was quite light compared to my normal flow, although more than just spotting. What's more is that it only lasted 2.5 days. I never tested, but at first thought maybe I just had an anovulatory cycle. I did confirm ovulation with bbt though, and even had very light ovulation spotting during that time, so I'm pretty certain I did ovulate this cycle. What do you ladies think? I'm wondering if I should take a test in a week just to be sure, or if I'm just grasping at straws and should just chalk it up to a wonky cycle this month? If anyone here has ever had a late, light, short AF, it would be so appreciated if you could share the outcome of your situation! Thanks all for reading!!
