You know I think sometimes epidurals get a bad press but as a Doula, I do believe they have their place.
If you are scared you will not labour well, that is a fact, I'mnot saying you won't labour but fear breeds pain, pain causes more fear.
If you are fearful, please do ask for an epi before they start a drip. I don't know how they plan on augmenting your labour, ie pessary, or other but if they are going straight for water break, I would ask them to clarify where exactly your baby is, how low is the head, how favourable you are. These things will have a bearing on how long and how successful induction will be.
You can insist on a epi before the water break or as near after as you can, I do believe an epi gives some women the confidence to let go of the fear and really relax into the labour. Perhaps ask if they do a mobile version which will give you the option of mobilising yourself therefore letting gravity help.
Having said all of this, Thursday is still 2 days away. Have you thought of Evening primrose capsules, inserted at night forthe next night or so, some say it can help to soften the cervix, Please DO NOT take caster oil, it can be dangerous for the baby, and cause you to have terrible diareah, (sp) and who wants to go into labour with that? Raspberry leaf won't push you into labour either.
Sex and/or argasm may have some effect as the prostglandins that are present in semen are the same albeit natural version of prostin.
Please try not to be scared, have you a cd of something you find relaxing you could listen to?
