Cramping & spotting

Susie

I’m 6 weeks today & have been having about mild cramps. I had light pink spotting 4 days ago & showed my doctor at my last appointment the other day & she said she wasn’t concerned about it & it would happen more during my pregnancy. She said my ultrasound scans came back perfect & there was no bleeding so she wasn’t concerned at all. Now, I have been spotting dark brown discharge since yesterday & I’m pretty nervous. I’m trying to talk myself down from panicking but it’s been kind of a lot. Does anyone know what this mean? My next appointment is in 2 weeks for another ultrasound.
