7 days after your EDD is not overdue, and if you are not happy then you have the right to say no. Many women have regular scans to check placental function and fluid levels and wait until their body labours on their own. If you do decide to accept their offer of induction then at each stage you have the right to say no (for example if they break your waters and want to put up a drip straight away you can ask them to wait, even for a little while. If you are hooked up to the constant monitoring belts then it is difficult to move, but you can certainly go on all fours or on a birthing ball by the side of the bed. If you need to go to the toilet you can take them off. In fact I know a lot of midwives encourage women to "need" frequent loo breaks to ensure they get time off the belts and space to move. Getting in the shower or bath may be more difficult unless they have the waterproof CTG units, but if you are not on the drip then there should be no reason for constant monitoring. Perhaps you could agree to a CTG for 20 minutes every hour if they are insistent, and then you will have 40 minutes where you can hop in the bath or shower.

Obviously the above is only appropriate if everything remains well with you and bub. Best of luck.
