Implantation bleeding stories?

[Lismilo117]

Hi ladies, from my OPK’s I should be around 13dpo. I went to the toilet and when I wiped I had bright red blood on the tissue and assumed AF was here. I put in a tampon but when I pulled it out later it was clean. I’ve had no more blood (it’s been about 12 hours) but I have been cramping since yesterday and testing bfn. Could this have been implantation? The bright color and timing threw me off. What are your stories?

I had very dark brown thick mucus starting 10DPO - ending 13DPO. Tested positive 12DPO. It was a strong line so I reckon I would have tested positive sooner.

I have very light pink spotting in both pregnancies until about 12 weeks along with crappy stretchy pains
