I believe most doctors want your hcg to rise 66% - the "doubling" is a myth. At some point in time, I believe your hcg levels off a bit more.
I would call your doctor and inquire about progesterone. My doctor had me on prometrium 3xday until the 10th week.
Good luck.
Hello,
That is correct, studies in viable intrauterine pregnancies have reported the following changes in serum hCG:
-The mean doubling time for the hormone ranges from 1.4 to 2.1 days in early pregnancy (hence the repeating ~ every 48hrs until a diagnosis made).
-In 85 percent of viable intrauterine pregnancies the hCG concentration rises by at least 66 percent every 48 hours during the first 40 days of pregnancy; only 15 percent of viable pregnancies have a rate of rise less than this threshold.
-The slowest recorded rise over 48 hours associated with a viable intrauterine pregnancy was 53 percent.
Based upon what you report, your hCG seems to be rising okay. Given this is a spontaneous pregnancy it is unclear if supplemental progesterone will be helpful. In my patients I don't continue to check Progesterone levels in these circumstances as they are not any more helpful than following the hCG.
Best regards,
Dr. Downing
