Brown spotting

M 👱🏼‍♀️
I'm almost 8 weeks and I've had brown spotting off and on for past week. When it started my doc had my levels drawn and they doubled which the doctor said was reassuring. I'm still so nervous and I don't have my appointment until Tuesday. Would it be worth even calling tomorrow to see if I can be seen sooner? They normally won't see you until 8-10 weeks.
