Early HCG levels

After many years of trying, we started seeing a RE this year.  We were finally able to get pregnant in February.  At two weeks, my first Hcg level was 207.  We lost the baby at eight weeks and had to go through a D&E.  We just found out today that we are pregnant again, but at two weeks, my Hcg level was only 171 this time.  Should I be concerned that the level wasn't as high as the first time around??????  What could cause it to be lower this time?  I know I am probably being paranoid over nothing, but sure could use some feedback here!

All I know on th Hcg levels is from the first blood test to the second your number should at least double.

We won't have our second Hcg level tested until July 2nd - seems like it is light years away - and way too much time to worry if its normal for the numbers to flucuate this way

Yeah... Im kind of surprised that they are waiting that long in between tests... I had my first one on a friday and the next on a monday.  They never told me my numbers but there wasn't much of a change.  But that was because my baby stopped developing at 5 weeks and I carried it until I was supposed to be 13 weeks then miscarried.

it is really weird that they are waiting that long.  at that point your numbers really wont mean anything.  the first test tells you whether you are pregnant basically, the second should be two days later and see if it doubles.  HOWEVER, if it doesnt double dont freak out.  mine only went up 20% in two days and the dr told me i was having a miscarriage.  i am currently 30 weeks pregnant now with a healthy baby boy.  it is really the u/s and seeing the heartbeat that will tell you the most.  Good Luck.

The numbers need to double. That's what's important. When you say 2wks I'm going to assume you mean 4wks pregnant, 2 wks since conception.
Here's a good site with listed HCG lvls.

That number sounds fine for 4wks.

An excellent site for hcg levels is www.betabase.info.  It has levels for multiple and single pregnacies, allows you to track your hcg levels, also has a doubling calculator.  I found it very helpful.

my hcg was 37 at 2 weeks from ovulation then 1 week later 860 and 3days later 3426.
