It doesn't matter what the number is. It matters that it doubles in 48-72 hours apart. I have had mine not double the first time and she is almost 3. I'm not agreeing with the dr. right now as I don't think they can judge from just these 2 #'s. You said you had them taken 3x, what was the 3rd? Like I said, it doesn't matter what they begin with. This new baby for me I started with a 28! The spectrum is huge if you type in google hcg levels.
HI My HCGs are usually around 100 at four vweeks and my OB said all is normal. AS long as doubling every 2 or 3 days. My OB office actually got my numbers wrong in chart and had me all worried but was just mistake. Believe in good and try to have hope and try not to worry. My first 2 babies were fine. Also what time of day I think can affect levels. So if you were 97 on Mon. afternoon and 200 on Thurs. morning? Just guesing here and offices do make clerical errors on occation. I have never heard that 500 is normal at 4 weeks ! Look that one up in wikipedia there is more like a broad range of normal hcg levels. Good luck, Kristin762
