Women & Toilet Selfies WTF?

Recently met a cute girl - possibility of dating - added her on Snap. She just started working at a store I frequent close to where I live. Our banter is somewhat flirty, mostly friendly, we're both in our 30's. There's no doubt in my mind where this thing will go in the near future, but the situation is complex. I'm not trying to make anything happen and I'm just going with the flow.

That being said, first day I added her on Snap, she sent me a pic of her sitting on the toilet. I think nothing of this, and pretty much ignored it as I didn't understand wtf it meant, if anything. A few days go by and she sends another one using the Beard filter (we have an ongoing inside joke about her awesome 'moustache' - hence the beard filter), in the second 'toilet selfie' the pic also shows that the toilet paper is out.

I have zero idea how to interpret this. I would love to get some honest, objective input from women about what a selfie of a woman sitting on the toilet means. I have some theories, but I would like to know exactly what the meaning of a pic like this is. It's not a 'bathroom' selfie - it's a selfie of her literally sitting on the toilet doing her business, just for clarification!
