Non Profit Board Member Interview

OK, if you are early in your career / have no idea about this, pls don't try to chime in here. 

I am 33 and have about 8-9 years of WE, which I shared to indicate I am not a new kid around the block. 

I have never sat on a board of a non profit and have been looking for avenues to serve the society (as well as meet new people, in particular ladies). I came across a four decade old non profit whose trying to eradicate a disease that means a lot to me, so I went to their website, shot an email to a generic email address listed there, and a few days later, the COO of the non profit reached out to me to schedule a time for us to connect. She told me they were looking to recruit four board members and shared a job posting. 

I spoke with the COO a day later over video and it went well. We spoke about for 35 minutes wherein I asked her the questions that were on my mind (99% of the time was spent answering my qs) and then she asked me to tell me about herself. She volunteered that if I was interested, I should share my resume with her, which she could then pass it on to the audit committee at the non profit, whose reviewing resumes. Later during the same day, I sent her my resume, saying it was a pleasure speaking with her and as requested, I have attached my resume. She responded an hour or so later with "Thank you, received and passed it to the appropriate people for review, I enjoyed our conversation today! Have a great evening! (Glad you decided to apply!)." 

Now, it's been a week, and I haven't heard back from the non profit or anyone. And I wonder if I am expected to follow up. I have no idea how to carry yourself in these matters. Obviously if this was a job interview, I would have followed up. The easiest thing is to forget about it and move on, as if they are interested, they know how to contact me, but knowing myself, it's important for me to get closure on things. 

SO, all that is to say, is should I follow up? If so, what do I say? As I mentioned, this was my first ever non profit board interview, and so I don't know what are the SOPs. For reference, most people on the board are boomers (partners at banks, law firms etc.)
