flightatendant..
well hats off to you for having faith in yourself to birth at home, a lot of people would perhaps doubt their ability. by the sounds of it you did it all on your own last time and that is a good indicator that you will not need any inervention again, it's just a question of getting back that confidence and putting yourself and dh in control.
have you managed to meet some of the midwives likely to attend you? that might be an idea.(although you said you only have one appointment left...) I think it is very important that who ever is on your hb rota is fully aware that you had problems last time though no fault of your own. maybe your mw can write some notes on the rota that she sends out to whoever is on call if she is 'too pushed' to speak to them individually -maybe you could trace their phone numbers in order to voice your concerns.
I had a miss-managed birth (told to push for 2 hours when only 6 cm dilated by a very in-experienced mw) for me it didnt effect the second stage and I swapped to a very good mw who saved the day. but as a result I have forced myself to put-out-the-vibe that I am very 'precious' and expect almost special treatment (am due in a week ish 3rd baby and homebirth) I have managed to keep the mw on side by not being a pita about it, but as a result of my assertiveness I have her very much on side.
I totally understand why you didnt take it any further, I felt exactly the same as you and fortunatly the team manager took action for me and the mw ended up having to leave the community and have supervised practice in the hospital for 6 months.
You probably get the idea that I am all up for natural hands-off type births, and struggle with the way our maternity services are so medicalised. I understand how you feel completely about being scared of a repeat situation, but actually you have 5 weeks, enough time to get all that confidence back again, put yourself in control, you have done it once, you are already in a better position because you know you can do it (go into labour, contract, dilate, push a baby out). same for your dh.
there are heaps of practical things you can do too, dh is your gatekeeper while you are giving birth, you will be busy!
sorry for the long post, I could bang on for ages, but if you need some ideas for how to feel more in control, I can recommend some reading.
