Miscarriage questions?

I'm 7 weeks along and I'm expecting to miscarry. I think it may have started, but I'm not sure. I've never been pregnant until now.

I don't go to doctors so I'm relying on pregnancy tests and periods to confirm the miscarriage. I'd just like to know what to expect.

What does it feel like physically?
How long do the miscarriage symptoms last? How long do normal pregnancy symptoms last after miscarriage?
How long after miscarriage until a pregnancy test can read negative?
How long after miscarriage until my period will come back?
