I totally agree with AHBD, I don't think you have any reason to worry at all here, nor any need for a vet. First of all, these are not symptoms of parasites at all, if she was having very runny stools that are very smelly then that would indicate Coccidia, but that's not the case. And honestly, the last thing you want to do right now is take her to that vet, who obviously doesn't know a whole lot about dragons at all, and have him put her on an antiprotozoan or antiparasitic medication right now for either no reason, or even a low to moderate count/load of coccidia or pinworms, which doesn't need to be treated (Only if the counts are moderate to high should you medicate for coccidia or pinworms). It's a very common and unfortunate occurrence for exotics vets to put dragons on meds for parasites when it's not necessary, and all this does is start a vicious downward spiral, as the meds are extremely harsh on them and usually cause a total loss of appetite, severe lethargy, and sometimes worse...
Again, I think it's one of two things: #1) Follicles and/or eggs, or #2) It's the usual hormonal behavior they exhibit at this age, combined with the winter blues. My year and 1 month old girl has not been eating half of what she typically does, and for whatever reason this season is really causing a lot of this, it's all over the forum.
If you can get to do an ultrasound without trying to sell you things or give her unnecessary meds then that's one thing, I just have a really bad feeling that this vet is the type that will not want to run any diagnostic tests but will still prescribe harsh antiparasitic meds that are only going to make her very sick, when she's not sick to begin with. And if she has follicles or is developing eggs, which is likely, it does take time.
Her frantic behavior certainly isn't indicative of parasite, an infection, or other illness, as with parasite and the like they behave exactly the opposite of the way she is behaving, they just lay out of the light and sleep all day long. I think she's fine, and I think that vet got you worked up over nothing at all. I'm still shocked about him talking to you about spaying her and trying to sell you pet insurance to cover the spay surgery when he didn't even know if she had follicles or eggs. That's red flag...(by the way, if you request a plain x-ray and he doesn't see eggs, that doesn't mean she doesn't have follicles and isn't going to lay eggs soon, that's why I suggest the ultrasound, it will confirm or rule-out follicles and/or eggs)...
