Premolt or Prebrood?

Here are a couple of angles of my girl Eve. Is she premolt or pre-brood? I thought for sure she was 7i, 1.5 yr. ago. I could have missed an instar and she 8i and pg. My male died 1/16/13. Any thoughts? She is cb born 8/24/11
She's already 2 yrs 3 mo, I thought she would've made it to 8i by now. Maybe not!!! She's isolated now.

I wanna say premolt because I *think* I can see evidence of a new exoskeleton forming underneath. However, I'm not sure if that black stripe has always shown through the pleural mambrane.
