My wife pregnancy 20 week complete, cervix 2.5 cm , back pain, so admitted in hospital, please precautions and doctor ideas

In this condition if she has been admitted then it is important to perform a ceclage t surgery so that premature delivery can be prevented and from now on since you are already in hospital when you will reach your home it is important that for minimum two months you should do a complete bed rest which will mean that you can only sit up to have food and go to have bathroom and loop otherwise you have to to keep sleeping on bed most of the time I will advise you to not to worry speak about the preventive surgery which I have mentioned
