pregnant or not?

Hello, future moms.

I have a very urgent question and based on what I've looked up, it might actually be spot on. But if anyone wants to chat about what I'm thinking or feeling, I hope I can figure things out.

On Feb 8, I started bleeding.
On Feb 14, 7 days later, this should have stopped, but I kept bleeding until Feb 20.

Between Feb 20 and 24, I'm most fertile according to my ovulation calendar.

On Saturday, Feb 27, implantation should have occurred, and that was exactly one week after my period stopped on Feb 20.

According to my calendar, implantation falls exactly on Feb 27, and I had a very light bleed that evening. It didn't continue.

Now I should get my period this Sunday, and I can test as early as March 3.

I have no symptoms except for a slightly bloated stomach with some cramps and a slightly discolored nipple, but nothing too severe.

What should I make of this? Could it really be true?
I hope someone responds and maybe thinks the same.

Love,
