US Immigration from Philippines

I am confused about calculating household size.. It is just me and my son so would that be 2 or would it be me, my son, and my fiance to make it 3?

Do I include my fiance on the household size because when she gets here it will be 3.. or are they asking current which would be 2?

I got charged the application fee but haven't received a receipt or appointment notice. My green card expires on 7/18/2020. I'm really worried about having an expired immigration document.

On February 18, 2020 we interviewed at USEM and application was approved. There was a tremendous amount of confusion due to the pending Corona Virus and the Visa was issued on the 26th of February and held up from issue on the 27th. Everything was in turmoil , lost paperwork, no communication etc etc. I had to leave and now fast forward 5 months and no activity on our Visa. My Fiance claims that the reason there has been no update to the CEAC is because I have not called USCIS. I am trying to tell her it is because the Embassy is not processing K1 Visa's at this time. Stress is building because she claims people on her Facebook claim that some are getting updates and have even been issued a visa. She thinks I am not trying to help with getting the Visa issued. Is there anything I can do to push this pending Visa? The Embassy has acknowledged that they have all required paperwork.

green card interview was supposed to be mar. 30, 2020, of course it was cancelled due to covid, has anyone had and progress of similar cases?. i have looking on here , but the site is hard to navigate , i keep getting info from past years, just wondering whats been happening,,also her EAD will expire on jan11. 2021, so wondering if we need to apply for another soon because she is working and i really dont think the green card will come soon enough. thanks
