Testing help

So for years my cycle has been 28-29 days, with the occasional early or late a day or two. The last 3-4 months however, it’s dropped to every 25 days, which I usually start spotting on cd25 before af is full blown by the next day. Here it is cd25 today and no sign of af. No sore boobs, no cramps, nothing. My question is, when do I test without it being too early. Will I go by my more recent cycles and test tomorrow or the next day? Or wait until cd 29-30? Over the last 5 years I’ve trashed a lot of tests... but I still wanna know as early as possible... input or advice? TIA
