Could be hemipenal sheds, when the water bowl will look like "V" or "X". Probably a more correct term for them?????
Number one indicator for mine is the refusal of food, pretty much all of my females will stop eating, some will occasionally take a small prey item but none will gorge themselves like they will in the months just prior to breeding seaon. Other signs of gravidity:
Sometimes you can see the swelling and /or feel the individual egg follicals.
A gravid female will assume odd positions including upside down in efforts to thermoregulate her body.....the incubator for her eggs.
The thickest part will typically start mid body and extend down towards the vent.
Once you've seen a gravid female, all the weight and body proportion symptoms will be obvious.
