Is it normal to have some brown spotting or brown tinged cm during early pregnancy?

Britney • I'm a happily married to the love of my life and I'm a 27 year old who is graduating university soon this year and is hoping to start having some beautiful babies soon! We have had one pregnancy and miscarriage at 7 weeks so far hoping for a rainbow baby
My doctor said as long as it is not alot it's completely normal but I am still worried! It looked like there was a tiny bit of clotting and then brown tinged cm is this normal? Pls don't worry me I'm already super worried! Lol I'm 5 weeks 5 days today I have been having a whole bunch of other symptoms and positive pregnancy tests still so that's good I'm just worried! Pls help
