I'm 4 weeks and 1 day. My first HGC test the level was 454. I went to the doctor last Thursday and my Hgc level was 639 so  I was scheduled another appointment for today meaning it's been four days since my last test and the results for today's test was 1156. I was told that the level was to low and I only doubled once instead of twice over the four day period. Then I was taken for an ultra sound again and still nothing which I expected because I know it's still pretty early. Now I have to go back Friday to repeat the test. It's nerve wrecking that I have to go through this ever two to four days to hear my HGC levels aren't high enough
