Moving out of state while 31 weeks pregnant: best options for insurance?

Hi, I have BCBS of MI coverage currently. We will be moving to CA for my husbands new job, and there will be a 1.5 month gap in employment during this move. His work is offering insurance with a smaller network and will limit my options to 3 hospitals. This insurance can go into effect August 1. I’m pregnant and due August 15.

Would you find a marketplace? COBRA, then switch to husband? Or COBRA and stay on cobra since my husband already hit his deductible and I will too once I have this baby? Will moving out of state impact the BCBS coverage? Help! I’m so confused.
