Brown discharge isit normal? Im at 6weeks! Its actually quite abit should i be worried?

I have been spotting brown since the day I missed my period. Yesterday was my first scan and I was 5w4d pregnant. After the scan, I started spotting (well quite a lot) of mixed brown and red discharge and I got scared and worried. It stopped after a few hours. I will monitor and will definitely contact my doctor if it happens again. But I am praying all is well.
