How likely is pregnancy?

Hello again, so this is in reference to my female Heterometrus silenus. I just got her 2 weeks ago. But yesterday when she decided to come out of her hide I noticed her side plates are separating (I don’t know the proper terms yet). I believe she is fully grown and somewhere between 1 and 3 years old, however, this is just a guestimation. Now I know their plates can separate due to things like pre-molt, eating well, and pregnancy. I don’t think she’s in pre-molt because again, I believe she’s fully grown. She does eat but not very much (she eats about every 3 days and will only take 1-2 medium dubia roaches and if I try to feed her more often she pushes them away) but drinks LOTS of water, I also mist her enclosure daily or every other day and the humidity stays between 70 and 85.
So my biggest question is what is the likely hood of her being pregnant?- or could she be in premolt and I’m just so off on her size and age? I unfortunately do not know if she’s CB or FC, or if she’s been around a male at all. Thank you in advance for any opinions!
Picture #1: November 19th- this one may be a little blurry but there was no plate separation.
Picture #2: yesterday (December 2nd)- dramatic plate separation versus 2 weeks ago.

That not evidence of being gravid that is the pleural membrane nothing more. All scorpions have this feature.

She doesn't look very fat, and with that frequency of feeding it is expected that she will gain weight. One appropriate sized meal every week or even every other week is plenty for an adult.

Most Heterometrus sp are wild caught, so it's possible....but this one doesn't look gravid by body size
