ah, sorry to hear you are so worried
basically, when you are induced, and of course many women don't need inducing.. you are induced on the ante natal ward and are subject to the visiting hours, which are usually for many hours, but once it islate evening, visitors are asked to leave
some women are on teh ante natal ward for bed rest , some are in for inductions, some for monitoring etc and having a ward full of women ,all of whom need to rest, is not an apporpriate place for lots of extra people.
if you are on the ante natal ward and in pain, then you should be looked after, offered apporpirate pain relief. such as a bath, codeine/paracetomal, some units offer gas and air on teh AN ward. you can't have stronger pain relief though
as soon as you are in establised labour you will be transferred to the labour ward, where your birth partner can be with you until delviery
try not to worry now about induction and complications, many many women have totally straightforward pregnancies and births.
also, you might want to look into hypnobirthing or having a doula with you for support
i am a birth doula and have been allowed to stay in a side room with a woman being induced so she is not alone
