Congrats on the VBAC!
I absolutely recommend you wait until you stop bleeding.
I know what you're saying. I was feeling in the mood at 4 days postpartum (only in between my monster afterpains). But even though I was "in the mood," I knew my body wasn't ready. When we first tried at 5 weeks pp, I was just barely ready, physically speaking.
That's w/ my second birth. With the first one, I thought I was totally ready at 6 weeks. YEAOUCH! (I had had a 2nd degree tear that time.) But by 8 weeks I was ok.
The lochia (bleeding) indicates your body is still healing. I am in favor of respecting that, and waiting until the flow has totally stopped, before you have intercourse. (And some people wait longer than that, but that depends on how you feel, how long you bleed, and whether you suffered tissue damage or not.)
On the other hand, some midwives give the go-ahead at 3 weeks regardless, and I know some people wait only 1 week and nothing bad has happened as a result that I know of.
