Spotting the day after sex ?

I had sex multiple times this month..but lets focus on last night. He always pulls out, and he did last night too..but I noticed a lot coming out of me, I guess he wasn't quick enough. I ovulate in "2 days" according to Glow. This morning, very pink watery discharge with what appears to be small bright red " flakes" of blood. Is this moat likely ovulation or could it be implantation?
