Changing medical Insurance during 3rd Trimester

I need some advice/guidance. I’m 32 weeks pregnant. I am currently in a PPO insurance and have seen my doctor throughout the entire pregnancy.

Looking into the co-payments plus labor and deliver it will be approximately $3,000 for everything.

Now my employer is finally offering Kaiser insurance.... same monthly payments..... total visits, labor and delivery will cost me less than $100.

I’m torn and don’t know if I should switch during this open enrollment in time for me to deliver.

I’m not necessarily married to my current doctor (he informed me he will be on vacation the week before my due date and return the week of. So likely he won’t be even be there)

I’m a FTM and I have never had Kaiser, I just hear it’s great.

I know if I switch now I will only have to pay for the doctors visits (approx. $300-500) that I had with my current doctor.

Anyone have Kaiser that could give me some advice?

The Kaiser insurance will come into effect Feb 1st which I will be 35 weeks.

Is this enough time to find a Kaiser Ob/gyn?

Has anyone switched or gone through a last minute change during 3rd trimester?

Thank you in advance. Any advice will help.
