Brown Discharge (pic attached)

I'm currently 10 wks & 2 days. I started experiencing brown discharge on Christmas Day. Went to the ER and baby was still ok with heartbeat of 167 bpm. Doctor followed up tuesday and was able to also find hb with Doppler. Discharge went away Thursday but this morning it's back again! I'm beyond stressed out bc of my previous MC. Doctor office is closed tomorrow and I have a appt on Tuesday. Has ANYONE else experienced this and everything came out okay? Looking for some reassurance! 😢
