I had my first hcg test last Tuesday and it came back at 8.  The next test was Thursday and came back at 49. That's 6 x's higher in just 2 days! On Saturday, I took a CB Advanced and got 2-3 weeks. I read it takes a hcg about 200 to read 2-3 weeks. I went from 8 to 2-3 weeks in 4 days! I spoke to my dr's nurse and said is that normal to increase that fast!? She said, "Yeah if you're having 5 kids!" 😬 I know she was joking, but...Gulp! She's checking with the dr and deciding what to do next. Meanwhile I'm sweating bullets! I had higher numbers with my last, but not this high!
