BPJ,

I am no expert on your situation as I also am a member of the non-uterine club. However, in regards to the backpack Jac (small pun), maybe switching to a messenger bag is worth considering while doing you urban jaunts. It could be a big more manageable in terms of load-bearing. Just a thought.

I am glad to hear things are progressing well for you.

My $.02
