My wife and I have been trying desparetly to get preg for 3 years. We
finally got some good news this month. She was 10 days late and a home
preg. test came back positive. We went to the Dr.'s to confirm and sure
enough it was positive. Her HCG level was in the 500's, but her
progesterone level was low. She started taking injections of
progesterone two days ago (Dr.'s orders) and the Dr. wants to retest
her levels today. Is this normal? Is the HCG level low? So confusing!


Here's a great website with info about HCG levels, doubling rates, etc.
http://www.ivfer.com/hcg.htm

If this was a natural cycle (non IVF or IUI) you look at the "days post
HCG" chart, figure out how many days she is past ovulation, add one (HCG
shots induce ovulation 1 or 2 days later) and look at that relevant line.
If she is 10 days late, she's prob. approx. 24 days past ovulation, which is
too late to use the "early HCG levels and outcome" chart. If this was a
natural cycle, you can't really be sure about ovulation date, but if
charting should be able to make an estimate.

Once you get the second level, use the doubling calculator. This should be
more accurate because it doesn't depend on ovulation date.

Good luck!
