Lisa: I think you numbers are great! Check this out!

following table is a guide to what hCG levels can be during pregnancy.
For those of you who are interested, or are having hCG monitoring, here are the suggested reference ranges for a single baby pregnancy. As you can see the range of normal levels is very wide. hCG levels can be 30 to 50% higher than for a single baby pregnancy, in twin and multiple gestations.
Weeks of pregnancy
after last menstrual period Days after conception Approximate hCG levels
for single baby pregnancy (mIU/ml)
Weeks/Days after conception/Approx HCG levels
Week 3- 7 -0 to 5
Week 4 -14 (next period due) 5 to 430
Week 5 -21 -180 to 7400
Week 6 -28- 1,100 to 56,500
Weeks 7 to 8 -35 to 42 -7,600 to 230,000
Weeks 9 to 12- 49 to 70 -25,300 to 290,000
Weeks 13 to 16 -77 to 100 -14,000 to 243,000
Weeks 17 to 24 -4,000 to 165,000
Weeks 25 to birth of baby 3,200 to 90,000
4 to 6 weeks after birth Less than 5
These should be used as a guide only.
hCG levels double approximately every 48 hours during early normal pregnancy. It reaches a peak at about 10 week of gestation (since last menstrual period). At which time the average hCG levels in samples is around 60,000 mIU/ml. There is a very big variation in individual hCG concentrations. At this time, the extremes of normal levels are approximately 10,000 to 250,000 mIU/ml.
In the next 10 weeks (10 to 20 weeks of gestation), hCG levels decline, reaching a average concentration of about 15,000 mIU/ml. Again, wide variation is found among individuals, concentrations ranging from 3,000 to 90,000 mIU/ml. The hCG concentrations remains at around this level, and with this variation from this time until term (20 to 40 weeks of gestation

I was getting on to post a thread on this! I just got my first blood work today, and it was 350. I had NO idea what that meant, but this thread has helped! I've just started my 5th week, and have another blood test on Wednesday!quote
