6weeks 5 days and spotting

I’m freaking out..... yesterday evening when I got home from work I wiped after using the restroom only to find light pink brown spotting on the toilet paper. I have not had anymore after that time. I’m not having any cramping, but this is not reassuring as I different a missed miscarriage in June and was so excited to be pregnant again. I don’t know how to feel or act....... my first scan isn’t until next Thursday. I’m calling my dr office at 9am in hopes they can somehow get me in for my scan today...... I just want to be happy and have a healthy baby 😪 Anyone experience anything similar and have a healthy baby?
