Dropping hCG


Ok sooooo, I’m 9 weeks pregnant. I had my HCG done yesterday and it was 63,000. On the 11 of this month my HCG levels were 69,000. So clearly my levels are dropping. I also have a SCH, so it’s causing me to spot off an on. Anyone with any experience? Due to the holiday, I won’t be going to my OB till Monday for an ultrasound so I’m kinda stressed. When dose HCG typically decrease?
