I need some input ladies

Any success stories with late implantation? If I do get a bfp this cycle I think I would have implanted on day 9 or 10 depending on what day you count as ovulation. Everything I've read says it's best to implant on days 7 or 8. My last miscarriage I got a bfp 4 days before my period (had tested earlier) and it ended in miscarriage. I guess my question is, has anyone tested everyday until they got a late bfp and had a successful pregnancy?

I poas yesterday and today and got bfn, but this afternoon I had some pink and brown (small amount and very light) discharge when I wiped and cramps. I usually get cramps with my period after it arrives so this would be early and unusually early for me. I'm not convinced I'm definitely pregnant at all and kind of ruled it out since I had a bfn this morning with a 6 days earlier first response, but I think as soon as I started to cramp and spot my miscarriage anxiety started to kick in.

Sorry so long!
