Confirming my leopard geckos sex.

[Theshiggityshwa]

So out of curiosity, I wanted to know the sex of my leopard gecko a few days ago.
I happened to snap a photo of the underside too.

From what I assume, I think its definitely a she. I've had my leo for about a year now and its pretty well grown.
Just wondering if its safe to say I got myself a girl rather than a boy?

definately a girl!
