Hello!

I've just gotten a positive pregnancy test and am looking for advice about OBGYNs. This is my first pregnancy, and I feel like I have no idea what I'm doing. All my friends in DC have either never been pregnant, or had a lot of trouble TTC/serious risk factors, and ended up working with specialized providers. So I have nowhere but here to ask for advice.
I've been going to CWC in DC while TTC and have had mixed experiences. I liked both providers I have seen there, but I've found it annoyingly difficult to make appointments -- no reply when I try to make appointments through the portal (even though the answering machine always tells me to do so), long waits when calling on the phone, and inconsistent politeness from the people picking up. Then, the first provider I saw (DeSelms) was no longer with the practice when I tried to see her again, and the second (Bohan) apparently doesn't do actual pregnancies.
Now that I'm pregnant, I'm having some doubts and wondering if I should continue going to CWC, or if I should look elsewhere--and if so, where? Searching for "Capital Women's Care," I found a lot of old threads, but not a lot of newer ones.
On the one hand, I don't have any high risk factors (that I'm aware of yet / other than that I would be 35 at delivery), it's super convenient to have a metro-accessible OBGYN, and apparently CWC delivers at Sibley -- which seems to be considered a positive. On the other, I'm wondering if I should be more picky and not just go with the place that came up first in search results?
Seems like "Foxhall" is no longer delivering babies, and I'm not sure what other options may exist.
If it matters, I have GEHA insurance and live in Capitol Hill.
Also, what else do I need to be thinking about and researching at this point?
I appreciate any/all advice you can give me!
