HcG Levels??

Melissa • 35 years old and pregnant with baby #2. MC'd in dec at 11 weeks. Hoping this one sticks!!
Has anyone else done a quantitative HCG test? I am having one since I experienced some bleeding and cramping on Friday. This is baby #2 for me and I had a miscarriage in December. My level on Friday (at 3.5 weeks prego) was 252. Going in tmrw for the next test along with a progesterone check.
