Like everyone else said, she looks and sounds like she's building. You may want to get a round ceramic dog dish for a water bowl so she can better wrap and get more of her body surface in contact with the bowl. Get a bowl as big as you can but not so big that she cant fit between the bowl and the sides of her tub and keep the water level up a bit so it can conduct more of the heat from her body when she wraps. Make sure to check on her every day as an Ovulation only lasts about 24 hours and you don't want to miss it. However, once you see it, it is unmistakable because she will look like she's eaten something larger than you have ever given her and it will be in the bottom third of her body. Best of luck and I look forward to pics of baby worms later this year.
