A BFP but low HCG

[Helena16]

So I'm happyish! Got a BFP today from my blood test but my HCG level was only 41, which is too low. The nurse said it should be at least 50. They now want to test again on Friday. Has this happened to anyone else whose gone on to have a successful pregnancy? I'm 9dpt5dt. Guess I just need to wait and see, again!!

While this hasn't happened to me, I have seen it happen in this group before. Congratulations! Put your feet and relax, fingers crossed xxx

Thanks, did they have a successful pregnancy do you know? X

I am not sure in that people can go quiet in this group once immediate treatment is over. I have seen numbers double and quadruple in a couple of days. You have every reason to be cautiously optimistic though, it's so hard but try not to worry. Box set? Movies?! Xx

Will do thanks X

Hi Helena16. Yes, we do get successful pregnancies and live births with initial low hCG readings. The variation of "normal" is huge, so although you have one of the lower readings now, hopefully by the time you are tested again it should have doubled - trebled. I have included my chart so you can see what I mean. Thinking of you. Diane

from conception from LMP (mIU/ML or IU/L)

7 days 3 weeks 0 to 5

14 days 28 days 3 to 426

21 days 35 days 18 to 7,340

28 days 42 days 1080 to 56,500

35 - 42 days 49 - 56 days 7,650 to 229,000

43 - 64 days 57 - 78 days 25,700 to 288,000

57 - 78 days 79 - 100 days 13,300 to 253,000

17 - 24 weeks 2nd trimester 4060 to 65,400

25 wks to term 3rd trimester 3640 to 117,000

After several days postpartum nonpregnant levels (<5

Just wanted to let you know my HCG level went up to 165 today, so feeling much more positive. Cue the next 2WW for our scan! X

Meant to double every 48-72hrs. You've smashed that number congratulations! X
