CaptainBarnacle I agree that the advice got more over the top as my pregnancy progressed! but I had a previous history of unstable PP and 6 admissions with DD2 and those were the conditions attached to my being allowed to go home rather than stay in hospital. I was also not allowed to push a shopping trolley or carry anything. The instruction not to be more than 20 minutes from the hospital came at 31 weeks after about 4 admissions.
At 24 weeks I was told to stop work. Under pressure, they rescinded this down to 2 weeks signed off at home, then back to work. I followed the instructions and after 2 hours back in my sedate office job I was driving home again to readmit myself.
After that stay, I was allowed to work from home, part time only, visiting the office a maximum of once a week to collect/deliver work, but on the condition I didn't carry anything.
As time went on and I gad more problems, I was given more restrictions, but it was still better than the 4 weeks I spent in hospital prior to the birth of DD1, where I was not allowed to set foot outside the maternity ward, even to go to the coffee bar on site with DH.
I'm not saying OP will have the issues that I had. There are 2 kinds of PP, stable and unstable, and four different grades (1-4), I am unlucky as I had unstable grade 4, and I had that twice.
Most people, including 3 people I know are stable, have no problems, complete their pregnancy with a scheduled CS.
I hated following the advice I was given. After DD2 was born, I was advised not to gave any further children. But the OP should know it doesn't always go smoothly.
