DPO & symptoms anyone??

What dpo are you and what symptoms are you experiencing?
​I am 4dpo temp drop this morning( weird too early for implantation?) after got flushes before bed last night, started with a sore throat, had to have a nap after work as I was awfully tired! And having crazy mood swings... Maybe my brain playing tricks on me but ah well...
