5 weeks 3 days pregnant

3 days back I found out I’m pregnant with blood test and home test.

Today I have started spotting and I’m using panty liner.

I have constant mild cramping.

But I’m freaking out with the spotting, I do read this it’s normal but for how long the spotting is considered to be normal?

I did call my doctors office, it’s Saturday so first appointment is Monday only.
