when i was looking at my dragons earlier my (pregnant) female was sort of shaking her head, almost like vibrating it a bit, not like she was trying to shake something off it, more subtle than that. she did bulge her eyes for a second or two as well. any ideas? (mainly should i be worried?) i picked the male up for a bit and was standing watching her she did it maybe two or three times in about 10 min or so.
