Spotting once a week

Hi ladies so I have been spotting once a week since I been 5 weeks ( I am now 8 weeks and 3 day) I also have a few days I do cramp as well. I am just wondering if anyone has gone through the same thing? The spotting is only one time and only when I wipe and then it will go away. Is this normal and typical? It’s never bright red just light pink. My ultra sound appt is not till Wednesday 😩
