Yep, did most of these, but am here to bring hope, and possibly grief, to all of you as follows:
1 - I was convinced I was pg, so pulled apart a HPT old-fashioned, and YES,there was indeed a very very very faint line on the inside.
2 - it was ONLY 8 dpo, and it was...
3 - A BFP (do you use that expression here?, I only joined since having DS1)....
So, I know I'm just allowing you all to act crazy, but sometimes it really is worth going the extra mile 
PS
4 - for DS2 is was dpo 10, but I'd used about 6 tests by the time I got the positive result on day 10
PPS - In between the two pregnancies I did get a block of 4 months where AF was late, my boobs were sensitive and huge, and I felt sick, and it was all entirely in my mind, so it can actually send you mad. If only temporarily. Don't say I didn't warn you.
