Welcome to our little corner of MDC, Kristie.

I think that for most people planning UC, "unassisted birth" is a bit of a misnomer, because what they really mean is birth unassisted by a medically trained professional, not necessarily
literally unassisted. Many UCers actually do prefer assistance of some kind -- they might have the husband acting as midwife, for instance, or they might have female friends around for emotional support. One person's UC can look very different from another's. As I see it, then, this is basically a support thread that is for anyone whose plans fall outside of doctor or midwife-attended birth. "UC" may not be the most accurate label for all of us, but has out of convention become the one that is most convenient for us to use to identify ourselves to each other.
For myself, the reason that I have and will in the future birth UC, is that biologically ideal birth (which confers many benefits to the mother and baby) can only happen under certain conditions, those in which spontaneous, instinctive labor and birth can occur. These conditions are going to vary from person to person. But generally, I see assistance of any kind, as well as the feeling of being observed, as being an interference to the normal process.
Which answers part of the OP question. My answer to the other part is that, yes, I am almost certain that I am pregnant this time.

I could of course, still miscarry at some point since it is still early (4 weeks I think,) or I could just be having a very strange PMS that is lingering on and on and mimics pregnancy perfectly, or I suppose I could be entering early menopause.

:LOL But
intuitively I really feel that I am indeed pregnant. Got all the signs. Except for the little pink lines.

I am really interested, this time around, on seeing what it feels like to discover the pregnancy gradually, as women have done for millenia.
