Ok y’all help a sis out 😐

Idk how to calculate this. I know there’s a possibility of me being pregnant but by looking at this can you tell if I would’ve already implanted? I’m on my 3rd day of being late and I’m really just trying to understand this whole implantation thing. I didn’t have any bleeding but a week before my “period” I cramped on and off for 3/4 days. Now I’m having pelvic pain and lower back pain, and I’m nauseous from time to time when I haven’t eaten. I’m tryna rule out possibilities but I can’t at this point 😩
