Decreasing HCG level

Posted by Jenni on April 24, 1999 at 15:37:35
I started what seemed to be my period on April 12th after major abdonminal cramping that lasted only an hour.  Then after 9 days of dark brown tar like bleeding, I took a preg test (this past Tuesday) that came out positive.  My bleeding stopped that day.  The next day my progesterone level was at 6 and HCG level was 5000.  My DR prescribed progesterone supositories twice daily.  Then on Friday, my Hcg was at 4500.  The lab didn't complete my progesterone level, but I fear that I will miscarry because of the dip in my Hct level.  I haven't had any bleeding since this past Tuesday, April 20th, and only some teeny tiny twinges of pain in abdomin (abdomen) - similar to pains with my first (normal) pregnancy.  I am scheduled to take another quant beta and progesterone test this monday, April 26th, so I will know more at that time.  As for what we know now, how likely is it that this could be a good pregnancy?  I understand that a progesterone level under 5 will almost certainly not be a good pregnancy. Since I am right at the border and my Hcg decreased from 5000 to 4500, how likely is it that I will have a successful pregnancy?  Thanks!

Dear Jenni:
The combination of a flat or falling hCG pattern and progesterone level, before progesterone suppository treatment, below 15 ng/ml has a very guarded outlook. hCG levels do not date a pregnancy: the pattern is helpful to follow the trend of a developing or a resolving pregnancy.
