6W+3 🌈and terrified with light brown discharge. Help please!!

Hello Aug Mommies

I hope you all are doing well, I am having so much stress from work as well as being pregnant after loss, its kind of so difficult to keep a calm. Today I had little light brown discharge. I did call my OB she asked me to have pelvic rest and gave option to prepone ultrasound which is scheduled for Jan 2. I don’t know what to do, I want to get ultrasound but also afraid that being this early it might no show baby’s heartbeat. What do you all suggest? Thank you in advance!

UPDATE******

The discharge has increased than yesterday but not painful at all. Just had regular mild cramps. Ultrasound booked for Friday, I have a faith that baby will be healhty InshaAllah.
