BLUE TONGUE SKINKS

Hello All,
My female Merauke Toby had 7 babies back in December (she got pregnant from the previous owner). Lately she has been feeling really heavy and she has been eating a ton less than she normally does. My fiance thinks she might be pregnant again, but we havent had her with a male. I know that crested geckos can retain sperm, I was wondering if it is possible for them as well? She is pretty plump and round. What do you guys think?

Pictures?

I cant upload pics.

Here the pictures are:

This is what I typically see when I look at gravid females.. but some carry the bulge all through the body, as well.

has been reported in an eastern before,same circumstances,had babies,then without being with a male for 11 months after had another litter

I wouldn't class it as normal,though who knows,another thing to keep in mind is if female cycled,she could be full of unfertilised ova,so instead of having babies they drop slugs

does look very solid for a female merauke,especially your later pics,keep us posted on how she goes,could just be a fatty but cant rule anything out with these guys
