8 week spotting

I’m exactly 8 weeks today and I have my 1st ultrasound scheduled for this afternoon. To my shock this morning at 3:30 I woke up pee & when I wiped I started having light red spotting (these 3 tissues worth), not on my underwear at all. This photo was taken a couple hours later so the blood had dried and darkened a bit. No pain or cramping. The bleeding has stopped, just had a wipe of very light tan when I woke up at 7. I am absolutely worried sick..I had spotting another time at 5w5d that was light brown and less than this. Wondering if I have a SCH? No recent intercourse or anything, the only different thing was I took Tylenol before bed for a migraine. Will give an update after my scan this afternoon but has anyone else experienced something like this?
