Is this a male or a female?

Hello!
I recently purchased this 7 inch red foot as a female, but I honestly can't tell. There is a slight concavity, but it's nothing like my obvious males. Any thoughts?

Oh, and please excuse the paper on the plastron. It was a super quick photo session and I just wanted to record her condition.

Looks female at this point. Pretty too.

I would say female but someone that could tell for sure is @HermanniChris

Nice shell, I think female.

That's a girl alright.

Awesome, thank you all!
