Tmi FTM spotting

Emma • married, mommy of two angel babies👼🏻👼🏻TTC
I'm 8w2d today. I've had medium to light brown for past two days. No cramping but feeling of pressure. At 6 weeks my hcg levels were good. My doctor won't see me unless I have cramps or red spotting until 12 weeks. I understand that spotting might be quite common in 1st trimester but I haven't had it before, since bfp (no implantation spotting either). I'm so terribly terrified of a mc and I would like to know what would you do? And whether you had something like that and his did you deal with it? Thanks in advance.
