Hmm you know it's rather puzzling! I think there are ovaries there but I can't quite see, I know it's difficult to get pictures of them just right though. I'll give you some pictures to see if they will help too.
Here's 3 pictures of my females, first is Pineapple and the second I've outlined her ovaries so you can see them in the first picture and then spot them in the last one as well. The last one you can best see the ovipositer and ovaries on Emma, the white one at the top left and then Pineapple is in the middle there.
