Implantation experiences then bfp? Help x

[Ttcafterayear]

2 days ago, (13dpo day before period due) I started my 'period' but this is not a period.. it's a very very light flo no way near enough to fill a pad but I've had one on and it's caught trickles of it on both days and nothing during both nights! with moderate cramps, More when I wipe! today 3rd day it's small spotting only when I wipe no cramps no symptoms I feel amazing apart from a beadache! I'd feel like absolute poop by now what is going on?! Is it implantation anyone gone on with similar and bfp?

I noticed implant bleeding in 2 or 3 pregnancies. Both times, it was the tiniest, 2mm, yellow/brown speck on wiping. Nothing on underwear, nothing on a 2nd wipe and nothing the next time I went to the loo. Others have different experiences, so it doesn't mean you are out.
Have you tested?

Yeah negative, but an ovulation strip is slightly dark but not stronger than the line?
