Need advise

Monisha

Hi everyone I am currently at 11/12 dpo....but since morning have full ache in the lower abdomen ...and slight streak of blood in cm after bowel movement. I am not trying to symptom spot but have been etc for long now and I am hoping this to be an implantation bleeding. As I start spotting always just a day before af so this is really unusual for me ...as I still have atleast 3 days for my af. Anyone who had the same symptoms got bfp?
