VERY light spotting at 6w4d?

Ol

I’m currently 6w4d with my first pregnancy and I’m a bit concerned. 2 days ago around 7:30pm (after dinner) I had a slightly pink hue mixed with clear discharge when I wiped. It only happened once and didn’t see more that night. The next day around the same time, I had the same thing happen, this time slightly brown instead of pink. Today same time again, even less pink than before but still happening. It’s only once a day and only when I wipe. Has anyone had a similar experience? I don’t want to overreact but I haven’t found anyone who has similar issues.
