Yeah, I would expect the amount of variation on this to be huge. So here's my experience, for what it's worth.
I had a longish labor (21 hours) and the last 8 hours were difficult and excruciating. However, it was a NCB (no drugs, episiotomy, etc.). I was very relieved when my daughter was born and I wasn't in a lot of pain, though getting stitched up (2nd degree tear) was very painful as the local was only effective in patches. I mostly felt shaky and tired. The nurse helped me to the bathroom before she left us alone, which I was grateful for.
I did not experience a birth high, unfortunately. I don't understand why not; I had a NCB, BF right away, etc. Oh well.
I had very painful afterpains (like active labor, except I couldn't change position or do anything to make them more manageable, but had to sit there with the baby latched on in a lot of pain). It was difficult to breastfeed because it was so painful, and I was having trouble bonding for this reason. I was really upset that no one took me seriously when I tried to say what a problem this was for me. The afterpains lasted for at least 3-4 days after the birth (just don't remember the timeframe well).
I also found BF to be painful. I had blisters on my nipples and when the babe would latch on, it would be immediately painful for awhile. My breasts were overall sore, also.
My body felt misshapen and wrong. I didn't recognize myself in the mirror. I had low energy and stayed in bed naked, with my naked baby, which was the best part. I had expected I'd be feeling great, but, um, not so much. Not sure why, again, since I was healthy, young, and had a NCB, no extra blood loss or anything.
It took 4 weeks before I felt even remotely human again. When the stitches fell out at 10-14 days pp, I felt *much* better. Oh, warning, the first bowel movement hurt like heck, despite the stool softeners. I had one small hemerrhoid and could not believe how much it hurt.

I was somewhat frustrated with my pp experience. I thought a natural birth would mean an easier recovery, and I also thought I would just sort of bounce back. I expected to feel good enough to be out and about by 2 weeks pp, but that just wasn't the case. We did start going for short walks around 3 weeks pp because the weather warmed up a bit.
Lochia lasted to the long end of the range of normal, and I noticed that if I overdid it I'd bleed more and pass small clots, so I had to keep myself pretty sedentary.
Loved the babymooning but hated PP. Not looking forward to it again!
