3 days before AF

It is 8/13 Af is due 8/16, first day of last cycle was 7/20, has anyone gotten a positive this early? Is it TOO early to test? Lots of bloating, waking up at least 1-2 times in the middle of the night to pee, gas, lots of headaches making me feel sick to my stomach but not necessarily nauseous, and on the 11th I had pain in my left pelvic area (possibly implantation?) everyone knows how it is wanting to test right away🙄 just trying to save some possible let down!
