Spotting only when I wipe

Mostly in the mornings since 5+5, when I had brown and after that til today 6+2 pink. No pains, no cramps. No staining the pad There has been a lot going on physically, mowing the lawn, carrying weights etc....but I am so early. Should they affect me like that? First doctor's visit and scan is on the 6th of august and I am slightly freaking out. There is a possibility of twins in our family.
