Spotting in 7th week

Hi! I am in my 7th week of pregnancy and I started experiencing super faint pink/brown/mauve-ish blood on the tissue when I wiped. No clots, no bright red blood. This has continued for a few days. I am not experiencing too much pain, just super full cramps and a heaviness in my uterus. The picture below is from this morning, and this was the most I had seen, and the first time I saw it in the toilet. When I called my doctor's office when this first started they assured me it sounds like implantation bleeding. Did anyone else experience this at 7 weeks? Good news is also that I have my first appt on Monday. Praying everything is okay and this is nothing it worth about. 🙏
