Irregular cycles, but very early pink bleeding. Advice anyone??

[NickiDGirl]

Any women w/irregular cycles experience implantation bleeding? So my cycles range anywhere from 25-31 days. Ive been tracking my periods for a year now on an app and according to that i ovulated on Feb 20th. On Feb 25(cycle day 19 and 5dpo) i had very very light pink bleeding for 2 days only when i wiped. No need for a tampon. Then i bled for another 3 days still pink/red. Not heavily. (So 5 days of light and pink bleeding) And no more bleeding at 8 dpo. Not normal, my periods are never this early and are also usually heavy and bright/dark red. Today im 9 dpo and bfn. Should i count myself out? Im always tired, my nipple tingle from time to time, random nausea , and headaches and mild cramps. I stopped bleeding but still getting mild cramps. Anyone have any experiences or advice to share?
