Implantation bleeding 11 dpo??

Taren

Hi! I'm 11 DPO (first cycle after very early miscarriage) and had a small amount of bright red blood after checking my cm/cervix this morning. When I went to the bathroom 30 mins later there was no sign of blood.

Is 11 DPO too late for implantation bleeding? And in your experience, how long did implantation bleeding last?

I tested on DPO 9 and got a bfn...I know, too early. I wasn't planning to test again until DPO 14.

Thanks for any thoughts!
