I agree, the waiting is the hardest part. Hang in there sweetie!!
As far as how early, I've only been pg the 1 time and I got a faint, faint, faint line (and it was after me tossing the test in the trash and then looking at it later in the day (which they tell you not to do), I was 8dpo. I had the same thing happen the next day, and the next day

It was 11dpo when I took a test during the middle of the day, got an obvious line, followed by a digi that evening. I had a short LP, so I rarely even tested as my cycle would end 10/11dpo. I know many ladies though who don't get a BFP until much later, including one who got negatives 12-14dpo, then finally a BFP 16+ dpo. It varies so much.
