Brownish discharge after yoga

Hi!so yesterday I did some yoga..when I returned home and went to the bathroom,while I wiped I saw the tiniest amount of very light pink colour.i even out some of the tp inside my vg (I know but panicked) and there was nothing but a spot or so of extremely light pink.

Today after a whole day of walking I returned home and did the same thing to check and it was more but brown...I don’t see it when I wipe only if I “search” for it..I am 6 weeks and have no pain or anything else.i have my appointment on Monday but freaking out...any ideas on how worried I should be? Thank you
