They should have explained to you why you were being sent upstairs and what the monitoring was for- before you had the monitoring. This is called informed consent- you need to understand what the procedure is so you are able to consent or dissent (say no).

If something happens that you don't understand, it is your right to ask for them to explain, and give you time to think about whether you want to do what they are offering.

Pre-eclampsia is something that you want to be checked out, but you also need to know your rights, and not to have things done that you don't want to be done.

take care,
