Levels

Hey guys - first time pregnant! My due date based on my last period is 12/20/20 however they called today and said my level is only 218 which can mean that I’m only 2-3 weeks or I’m miscarrying.

I have been crampy on the left side Friday Saturday and today. I have been making a bowel movement more frequently which may be the cramping.

When I went to the bathroom I had clear discharge with a brown spot in it. I wiped again and there was nothing. I am so scared that I am going to lose this baby as my husband and I have been trying for years. Anyone have something similar?
