6-7 weeks spotting too heavy?

Spencer • 26, dental hygienist, trying for baby #1

I started spotting last night. Really light. Light brown. No cramping. I tried not to worry but its gotten heavier and crampier. No more cramps than a period. Nothing like the miscarriage I've had. And the blood is still brown but thick? Im sure im losing another pregnancy. Just looking to see if anyone has had spotting like this and had it be ok. Im supposed to have an ultrasound Monday and almost positive its just going to be more bad news
