Rue - what a pain.
I only ended up with steroids as I presented with high bp at 36+6 and they have a policy to give them where birth is likely to be before 37 weeks. I was admitted because of the bp but it went down quickly on its own and so it was really the two steroids injections which kept me there.
Only one overnight in the end but I had to keep pestering to be discharged which happened at 10.30 at night!
Anyway, I would simply refuse. When I was in they said they wanted to keep a close eye on bgs but in reality I did all the checks and just reported back. The mws had no idea about diabetes, so completely stupid. As long as you promise to go in if levels consistently above a certain level , what difference is it to them?
And you get loads more rest thsn trying to sleep in a bloody hospitAl and avoid a lengthy hospital stay. At the end of the day they can't force you to be admitted so if you are dead set then just say no!!!
