Please send good vibes

Jenn • Mommy to Molly Luna (7-3-2017) and Ellie River (8-5-2019). Trying for our third (and last) baby 🤞🏻
I'm 8w6d and my first appt and u/s is scheduled for Tuesday. 
I've been cramping for a few days, which has been normal for me so far, but this morning when I wiped, there was brown (which I know is okay) but when I wiped again, there was also a lot of a diluted pink. When I called my obgyn, the nurse asked if I've had sex recently, and I haven't, so it's not from that.
As of now, there's only a little brown spotting, but I'm worrying because this time last year I was having a miscarriage and had a D&C on Dec 23. 
Anyway, my obgyn office is squeezing me in at 1:45 today, so please send good vibes my way.
