Thanks girls.

OK I found this on a website (Gotta love google):

3 weeks LMP: 5 - 50 mIU/ml
4 weeks LMP: 5 - 426 mIU/ml
5 weeks LMP: 18 - 7,340 mIU/ml
6 weeks LMP: 1,080 - 56,500 mIU/ml
7 - 8 weeks LMP: 7, 650 - 229,000 mIU/ml
9 - 12 weeks LMP: 25,700 - 288,000 mIU/ml
13 - 16 weeks LMP: 13,300 - 254,000 mIU/ml
17 - 24 weeks LMP: 4,060 - 165,400 mIU/ml
25 - 40 weeks LMP: 3,640 - 117,000 mIU/ml
Non-pregnant females: <5.0 mIU/ml
Postmenopausal females: <9.5 mIU/ml

So you would be 4-5 weeks from LMP??  Your range is still within the normal range from what I can gather but maybe someone else would be more helpful.

So that would make you around 19 or 20 days after ovulation? If so then yes it is a little on the low side. My HCG at 19dpo was 1178.

However, is it possible that you ovulated later than you think? Maybe you just aren't as far along as you thought?

Anther blood test should clarify it more for you as it should be doubling approximately every 48 hours at this stage.

Good luck!

For memory mine where about that at 5 weeks. My Dr also said it was low. I had repeated test and they doubled as they should and i'm now 23 weeks. So i wouldn't be too worried just yet. As long as the numbers go up as they should with the next test.

For around 5 weeks it is on the low side yes. But where HCG is concerned it's not the level that matters as long as it's increasing at a good rate. The only way you can really tell is to have a follow up.

Clarebare are those normal ranges, surely 18 wouldn't even be considered pg since most urine HPT's don't pick up anything under 25? Or are beta HCG's different to what's measured in urine?

Also, I'm still testing with first response, used my last one this morning but I've found that the last 3 tests, the test line colour has remained the same, not darker or lighter. Is this because 1)HCG isn't increasing or 2) the test lines only can go so dark? They are now the same if not a tiny bit darker than the control line.

Test lines will only go so dark and are not a good indicator of HCG anyway. My PG tests didn't go completely dark until my hcg was well into the thousands.

At 20dpo mine was only 185.  I now have a very healthy almost 6mth old DD!  I wouldn't worry too much, as long as it continues to go up (double) then it doesn't really matter what the initial number is!

I had a blood test 4 days before AF due (regular cycle) and it was 20, which is the "just" positive. I now have a cheeky 2 yr old as evidence original.gif There is such a wide range of "normal". It is better to go by the doubling rate then actual numerical value.

(sorry I dont chart etc so dont know all the abreviations  blush.gif )

ETA All HCG assays that I have used (ie blood test in Pathology) have 5-20 level as a "grey" are. Generally 20 is the minimum that is counted as POSITIVE.

The only way to know if things are okay is to get another blood test and see how quickly your levels are doubling.  There is quite a wide range of 'normal' levels and you may naturally be on the lower end.  Good luck.

I know how scary all of this is. Mine was 189 at 4 weeks 3 days but when I o'ed It could have been 4 weeks 1 day. The scan will give me a better idea.
Then nearly two weeks later that doctor rang to tell me my levels were low in his opinion. I told him no they werent but he put the fear into me and I worried my head off. I had another done at around 6 weeks and it came back as 8964. Then the next done three days later was 11,600. I should have been happy as but because it didnt double I freaked out but learnt later it doesnt double after around 6 weeks gestation or 6000 to 8000hcg.
My last one done came back as 26,500. So now I am happy. It does your head in doesnt it. Let us know how your next level goes. We are with you through this stressful first trimester,  wacko.gif  You will be ok.

Hi ladies not good news yesterday's hcg came back as 137. Went to for a scan to rule out ectopic but nothing could be seen so they couldn't rule it out either way.

Just a waiting game now and will need to do more hcg on monday. Thanks for the support here.
