Possible Miscarriage

I will be 8 weeks tomorrow and for the past week i have been having a lot of spotting. It started off light for 2 days then turned red and there has been some clots. I called my clinic and they recommended i go to urgent care. All urgent care could go was run some blood tests and a pelvic exam. They said my cervix looks closed which is good but now i have to wait two weeks for and ultrasound. Has anyone been through this before with previous pregnancy’s and end up having a miscarriage?
