Help????

Whens the soonest I can test y'all 😩 I haven't noticed really any spotting but I've been getting some dull kind of twingy aches in my lower abdomen and dull aches in my back and my boobs aren't really sore, but it feels like they're getting more sensitive as the days go on, and I never get this, this soon before AF is expected to come, it's only ever 2 days before. And ive been struggling so hard to not test way to early and it's killing me. So please, when's the earliest I can test?
