We highly recommend the Repti-Sun 10.0 strip fluorescent bulb and with that one, it should be 6 to 8" from her while in her basking spot.
www.petmountain.com has very reasonable prices. At a distance of 10 to 14", she's not getting much UVB at all but since you're using the Repti-Glo, I wouldn't put it any closer than 10" because that particular bulb has caused some health issues.
The swelling could be from laying eggs, are they quite large? Or, she could have one that is bigger and blocking her vent somewhat. Can you feel an egg near her vent? Does she seem to be pushing and nothing is coming out? If she is, then she should be checked by a vet so that an xray can be taken to make sure she isn't egg bound as that is a very serious situation and can actually kill them. That's why you need to watch her for signs of stress like darkened beard/and or tail, gaping frequently, change in her breathing, straining, lethargy, loss of appetite etc. If you see any of those signs, a vet needs to be seen asap.
What are her tank temps and what type of thermometer are you using? Does she have a laying box?
If you're not seeing any of those signs, continue with the frequent baths and also oral fluids as well as increasing her calcium intake.
