Have you got someone with you?
Ask the midwives to explain everything to you.
It is possible that bed rest can delay the onset of labour while you might be given magnesium sulphate to delay labour, steroids to help your baby's lungs develop and antibiotics to protect against infection. (Minimising internal examinations is also recommended).
At each step, ask the midwives or doctors to tell you what they advise, what the likely next steps are and what your options are. Being informed will reduce the questions you have and may reduce stress. Having soneone else with you will also help.
If your baby does arrive early, if you wish, you can ask to stay with them, as much as possible.
It is still possible that your baby may not be born soon, as the amniotic fluid could be from minor ruptures that self seal or the first layer of membranes. And while statistics can not predict what will happen in your situation, 30% of women who have positive partosure did not have their babies within 7 days. (That does not take account of other factors and does not give information about births beyond 7 days).
Wishing you and your baby all the calm you need and wishing you a host of wonderful staff around you both who will take care of you and your baby. Take each step as it comes, one at a time. Put yourself at the centre and keep all unhelpful people at a distance.
