TMI. Implantation Bleeding? Help

Amanda • one handsome boy (3-2-12) and expecting baby num.2 (8-12-16)
So woke up this morning, used restroom as normal, wiped, and saw light pink blood, small amount. Slightly tender breasts, very minimal cramping, back is hurting and mild headache, and very low energy/fatigued, indigestion. Slightly nauseous, but can keep food down. Not supposed to start aunt flow for another 22 days. I have also been forgetful, and slightly clumsy, dropping stuff. Had that with first pregnancy. Thoughts? Haven't tested yet. Plan on doing it in A.M.
