Dissapeared nuptual pad.

[Hypnotic]

I can't believe this, I'm stumped. A week or so ago, I took a picture of my frog showing a clear nuptual pad and assumed he was a male. While she was growing up, I always assumed she was female, she eats alot, has a really rounded head and is a really slow grower.
Now I'm beyond confused, a week ago he was a he, this week, no sign of a nuptual pad and she looks like a she... So yes, I am beyond confused. I've never read about dissapearing nuptual pads, I din'd even know such a thing was possible.
So I'm going to post alot of pictures underneath here, and I'm hoping the experts can confirm my baby is a female. My frog is exactly 2.7" or 7cm right now, and has never shown signs of a vocal sack, I also haven't heard a teenage croak yet, I would recognise it since my other frogs are all adult.
The first picture shows the "nuptual pad".

Honestly doesn't look like a pad to me in that first shot. I had same kind of thing happen with my female, I thought I saw a pad one day, got all excited and checked closer a few days later and it was really nothing

Yeah I can understand, but I've checked all my males while growing up, their nuptual pads all started the same way, but never dissapeared. I've checked my picture about a hundred times. It's not dirt and if it's not a nuptual pad, what was it?

Hm... Was it just on the one foot? If it didn't show up on both sides maybe it could've been a slightly irritated area (I know not likely given the coloring) or just some of the slight pattern-changes that happen as they get older? Still kind of weird.

Nuptial pads can fade on males during the off season, but they don't disappear completely. I don't believe that was a nuptial pad at all. They are usually much larger even when first developing.
