Implantation Bleeding after bfp?

[Babiesforme]

So my friend has thankfully and finally had a bfp at 10dpo. Today at 12dpo she says there was a tiny bit of pink when she did a second wipe after a wee. We've both been googling but I though I'd ask you lovely lot! Can you get implantation bleeding after a bfp? She says her period is due 14/15dpo

Unfortunately it's so hard to tell at this stage. I've had bleeding after a positive that turned in to a chemical, one a miscarriage and another 2 were pregnancies that caught.

I'm afraid only time will tell with this one. Good luck to your friend, I hope it sticks x
