IMPLANTATION BLEEDING?

Does this look like possible IB I'm about 7 days from my expected period.

The calendar below is an old screenshot!!

Todays now the 21st.

I definitely think it's a possiblity as it looked like old blood, and is gone now. I also had some mild cramping, and my boobs are sooo sore today.

Has anyone had IB around 7dpo
