nosnik, it sounds like your baby is settling deeper into your pelvis, and moving around to get ready fro birth
www.spinningbabies.com is a good site , if your baby is not in teh best position, to move him/her
if your baby is back to back, try to sit on a birth ball as much as possible, and avoid labouring lying on your back , which is not that great anyway
starlight, i thikn you need to take a step back and stop obsessing !!! you have 5 months to get sorted, new doulas are starting out all teh time, and you are bound to find someone
also, bear in mind, the benefits of a doula are immense and have been proven to be very useful, BUT, it is not a cast iron guarantee that things will go exactly as you write in your birth plan
she is there, whoever she is, whether, friend, mum, doula , whoever, to empower and support you and your DH into having a more positive birth experience this time
i still maintain that for you a homebirth , with the ability to move and vocalise as you wish would be a great benefit to you
