  Very high HCG at 3 weeks. WTF?!  (18 Posts) MightBeMad Fri
12-Apr-13 15:40:15  Op in my first pg I had a blood test at 5.5
weeks (English system - so 3.5 weeks after conception) and the
hcg came back at nearly 10000!! It was only one, heathly, baby
(now toddler). There can be massive variation in what 's
'normal' so don't panic. And congratulations grin  StiffyByng
Fri 12-Apr-13 14:57:26  In France the weeks aren't added, which
explains your confusion. It's also why we always hear that the
French consider a pregnancy to last 42 weeks when we expect 40,
because of the not adding the weeks. If that makes sense.
Congratulations too!  beckie90 Fri 12-Apr-13 14:12:15  HP is
right, you add 2wks onto the pregnancy although not in every
country some just count since conception, others from last
period. Mine at 5wks was 2200 (3 weeks from conception) and
36600 at 6 weeks (4wks from conception) mines just the one baby
and it was considered a normal level. So yours sounds normal.
