Nervous at 5weeks

I am 5wks 4days I started getting back pains and spotting 3 days ago. The spotting is brownish, and only when I wipe. I’ve had a molar pregnancy followed by a miscarriage and really hope that this is normal, but I can’t help to be overwhelmed and scared. My first appointment is Monday and I am patiently waiting but am also so scared to think this might be another heartbreak.. 🥺😢
