Brown discharge with pink now

Hey darlings quick question 
My OH and I had sex this morning and when I got up to go shower I noticed A LOT of brown discharge.. I mean it probably was a lot due to the CM, natural lubrication or whatever you'd like to call it. But it just kinda freaked me out.. And now after my shower I'm still wiping away the brown but it's turned into pink/reddish .
Other than that no other issues.. Just looking to ease my mind :) I'm 8 weeks tomorrow and my first appointment is on the 31st!
