These changes aren't anything to worry about, but it's neat that you're that aware of your snake's habits. One thought is that if her digestive tract isn't always as full as it used to be, then you might be able to feel the young (if present) a little easier. Remember that you're not underfeeding her now. She's just on a healthier diet.

Studies have been done on snakes where one group of females isn't fed for the last month (sometimes more) of their pregnancy while another group is fed normally. One of the goals were to determine whether feeding them affects the size of their litter or just the condition of the female after she gives birth. It turns out that the lack of food doesn't affect litter size, number or live young, or size of individual offspring. It just affects the condition of the female following birth (and perhaps her ability to have multiple litters in a single year). This isn't true for a lot of organisms, but it specifically applies to at least T. elegans and probably at least to Thamnophis sp. in general.
