You really will be fine, I know it feels scary but you will be OK.
Take a kindle/iPad for if you do have a lot of waiting around.
Make sure you have content downloaded or data so you can hotspot to your phone, otherwise you'll need to buy WiFi access at the hospital.
Chargers, headphones, several pairs of bottoms or a couple of skirts, mine got drenched when my waters went, and then again as I didn't realise that there could be further gushes after the first big one.
Snacks are really helpful as the food is minimal in hospital, I got a chicken sandwich at lunch, then dinner was a single sausage and a small lump of mash, breakfast the next day was a yoghurt and then a cheese sandwich at lunch, with 2 thin slices of bread a scrape of Marge and a barely there layer of cheese. If I hadn't had my bag of snacks I'd have been starving.
DD was born 6 years ago so we didn't have COVID to deal with, but DH came in with me initially, hung around for a few hours then when it became evident I was going to be there overnight hanging around I sent him home, there was no where for him to sleep on the ward and it didn't seem worth having him sat watching me from a chair. I think I sent him home about 4pm, then he came back about 9am the next morning. I was due to have the pessary checked first thing in the morning but everyone was busy so it wasn't checked till after 1pm at which point the broke my waters.
I assume once it looks like Labour is starting you'll be able to let your DH know so he can make his way in for the birth and be with you during the active Labour.
