Hopefully I'm worrying for nothing

Sorry if it's annoying with everyone always posting these FTM questions or what's going on. It's just nice to hear from other women who may have experienced the same thing. I was wondering if anyone has had yellow-tan-light brown discharge and everything was okay. I'm 9 weeks and 3 days today and actually just found the baby's heartbeat on the Doppler this morning but can't shake this nervousness about the discharge. It doesn't itch or burn and it's a very mild smell. It's enough for a panty liner. Idk if this is normal or what. My doctor said to take it easy and watch it and they'd do an ultrasound if it turns red but I can't help it. Please I would really appreciate it if anyone could share their experience. Thank you!
