Spotting at 5 weeks+ hcg

I started having spotting exactly at 5 weeks. It’s been light to medium pink. I know this can be normal but it’s very unsettling. It’s been on and off depending on what I’m doing (yardwork, straining, sex, etc).
my Hcg levels at 5 +2d was 9,979. At 5 +4days I’m 15,324. Which is a 54% increase, so it didn’t double.
anyone with a similar experience? I’m trying to get into my OB earlier but am getting married next week and don’t want to wait!
