Gut load and all looks good. I'm afraid that UVB bulb isn't going to be enough for her as she goes thru her pregnancies, You probably know one mating can produce 3-4 clutches of babies. The first one 6-9 months after her first mating and the others 3-4 months apart from there. She is using the calcium in her bones and body to calcify their skeletons. Your lighting and supplement schedule are even more critical for her than your male. You didn't list your schedule. I would give her the Repashy loD every two weeks and a plain calcium 2-3 days a week. If you are giving her more than that you could throw her balance off and cause bone abnormalities and metabolic problems. You don't need herpivite if you are using the Repashy.
Back to the lights. Those short or coiled bulbs don'r put out enough UVB for adults in full sized cages. I would upgrade to T5 5.0 or 6% for her ASAP. For now getting her outdoors for real sunlight once or twice a week could make up the difference.
If you think she's been getting too much D3 on your schedule you should read this.

IF the bumps spread or get larger rush to the vet. These guys do get infections and cancer like any other animal.
