Good luck tomorrow Andrew.
In terms of your question, probably fine for you to just message your partner when you’re ready to be picked up afterwards.
Every hospital’s different, some much more/less efficient than others. My experience was getting to a call time early afternoon and not being biopsied until I was the last one of the day at 4.30/5ish.
Others will have had more in n’ out experiences for sure. If I had mine again, I’d definitely take my EarPods and have a podcast or some tunes in my ears for much of the waiting time - particularly the second waiting room when it’s nearer my time to go in. I just think it’s nicer to be in your own bubble than have small talk or be listening out to others.
Go well, another poster used a wise phrase “leave your dignity at the door” when it’s your turn - I’d echo that. It’s an uncomfortable procedure but once you’re about ten mins into it, it doesn’t get any more uncomfortable. For me it was on a par with a root canal or a tooth extraction. Not fun, but not horrendous.
I had some post procedure bleeding, others don’t; some walked out fine, others walked out like John Wayne after he’d ridden across the Wild West. 😄
You’re getting it done, that’s the main thing.
