Implantation bleed?

[Whatnowthen82]

Hi all

About 14dpo now if not later and I thought I af had arrived yesterday but it only lasted about 4 hours, didn't fill a pad and was mostly brown.

I've also experienced more symptoms since this period has ended?? Sore boobs etc

Could this be an implantation bleed?

I only have cheap strips to test and 1 FRER. I haven't used the FRER yet but cheap ones are bfn.

Anyone experienced this? I'm totally thrown!

Thanks

I get some cycles with spotting before af and it’s not meant anything so far.
do you track ovulation? If not it’s impossible to tell if your period is late
