Implantation bleeding or not

Courtney • Married, mother of 3 + angel baby👼🏻🥰

Last week was one of the weirdest weeks for me; started Monday when I got a shower and the water felt like needles going through my nipples breasts aren’t sore just bad nipple pain/sensitivity when anything touches them. Then after work on thurs I stopped at the store on my way home to pick up a few food items and got lightheaded/dizzy followed by awful pelvic cramping-not normal AF cramps(these were lower a spread out close to my hip bones-ovary area) and a major headache too! So then on fri I hit CD 25 (due for AF 8/4, 6dpo) while at work mid-day I noticed some pink...could this be the reason I was cramping the night before? Anyone else think this could be implantation bleeding? This was the only time and day I’ve had this since.
