It sounds like you are a perfect candidate for a homebirth. I didnt start researching homebirth until about 16 weeks, but as soon as I started reading, watching videos and speaking to midwives I knew it was for me. Just think of the homebirth as the same as any other kind of birth (including a birth centre). If things are not going to plan, or the midwife feels she needs more help, then you can transfer to a hospital. My biggest positive about that is you're only going to get intervention when you actually need it...otherwise all else goes to plan and you breathe your baby earthside (or roar them there as the case may be) in your own home...its just magic.

Oh and on the GBS test, my midwife doesn't push this test because things can change so quickly...meaning you have the swab at 36 weeks and things are clear, but you have the babe at 41 weeks and you might have it. Do you have your hospital notes? I am also surprised you were 'let' to go for 3 days with broken waters...my waters broke and there was immediate talk of getting labour started because of the risk of infection...my midwife knew exactly what to suggest and things got going quickly.

HTH! Good luck with the decision.
