PLEASE what is this discharge?? 6 weeks pregnant

D

I’m getting discharge like this at least once a day for the pink and then quite often for the weaker colour throughout the day! The pink happens once a day when I go for a number 2! But the weaker colour happens on and off throughout the day. I am 6 weeks I got an early scan the other day at 5 weeks 5 days no heartbeat at that point as too early I’m not having an cramping or pains. Why is this happening??
