New Mom?

I know nothing about bugs and have never set out to keep a mantis as a pet. However, this mantis was hanging around outside my apartment for about two days, and laid eggs (ootheca?) right by my door yesterday. This morning when I left, I saw a mantis hanging by the door, and I assumed it was mama taking care of her eggs.

I researched a bit and am pretty sure this won't lead to a baby mantis infestation in my home. However, I am starting to get attached to mama mantis, and am worried about her (she's so small!) What're the odds she's safe through the birth of the babies? I can't take her inside, but are there things I can do to keep her safe?

Also, I'd love to know more about her. I'm in Northern CA, these are the best pictures I have of her - what kind of mantis is she?
