FTM Panicking over spotting at 6 weeks

Jessica • 29, Married. FTM to Sebastián James 11.30.19.

I check every time I wipe because I’ve waiting over 2 years for this baby so I’m so anxious for everything to go smooth. Now I do know that they say spotting can be perfectly normal, and more common in weeks 6 and 7, and it was barely pink when I wiped one time, after that morning. I don’t have bad cramps, just the normal occasional slight ones I’ve been having the whole time. How do you know what is normal and what’s cause for concern? My appointment is in 2 weeks to see my baby and I’ll be heartbroken if nothing is there
