3 days late and still bfns?

Kaitlyn

My AF was due August 1st. I have very regular cycles, like clockwork. July 31 (day before expected af), I got a bit of blood when I wiped in the morning. Put in a tampon but after that never had anymore blood and virtually nothing in that first tampon either. Fast forward to today and still no AF. I thought for sure it could be implantation bleeding but I just don’t know at this point. Still no sign of an actual AF (my periods always start heavy the first 2 days). And my breasts are still quite sore. I’ve taken hpts since the spotting but have gotten bfns. The picture is from today’s with second morning urine (I always have to pee around 2 at night so had to test with urine at 6). Today makes 3 days late for AF. I know it’s negative...just wishing I would either get AF or a bfp 😞 I’m so frustrated. Did this happen to anyone else?
