Spotting

Vikki

Hi everyone. I am roughly 13 dpo. And I have had a positive test. Since 10 and 11 dpo I’ve had brown spotting. Not enough for a pad and no fresh red, I’ve just been using a panty liner. It seems to of stopped but I’m left with this. What could it be? I have had ectopics, miscarriages and chemicals in the past, and I really feel like it’s going wrong again.
