Male Or Female?

[DustyTheGecko]

I've had dusty for over a year, and always thought of her as female, but now I'm uncertain. This is the first time I got a good view of her underside. Help?
If you need closer photos I can do that, but it felt weird in the moment.

Female. When crested geckos are male it's REALLY apparent.

I thought so, on other websites people said "If your unsure, it's female" but I just wanted a second opinion, Thank you!

There are charts on male and females. You can always wait some time. And don't forget a vet checkup.

How often do you recommend a vet check up for crested geckos?
