Pink spotting?

Hi I’m 6 weeks old exactly and I started spotting super light pink yesterday and today. It’s only visible when I wipe. I have very mild cramping. This is pregnancy #8 but baby #5. I’ve had 3 miscarriages before but it was super bad cramping and bleeding or missed miscarriage. I’ve never had light pink spotting so I don’t know what it could be. Has anyone ever had this? I will be calling my doctor tomorrow morning.. I have an appointment with him on Wednesday already. I’m freaking out by this. Let me know your personal experiences! Thank you in advance!
