Kimmy and Nae,

This is what is posted as a sticky in the first trimester general discussion thingo;

For those of you who are interested, or are having HCG monitoring, here are the suggested reference ranges:

Weeks Post LMP / Approximate HCG

3 - 4w: 9 - 130
4 - 5w: 75 - 2,600
5 - 6w: 850 - 20,800
6 - 7w: 4,000 - 100,200
7 - 12w: 11,500 - 289,000
12 - 16w: 18,300 - 137,000
16 - 29w: 1,400 - 53,000
29 - 41w: 940 - 60,000

You can see that the range is huge! This means that between 4 and 5 weeks it is normal to be anywhere between 75 and 2600! That is a big range. So looks to me like you are both doing well.

The "doubling every 2 days" is also a guide. I didnt double every 2 days with this baby, we had BT's every week for a few weeks and I am now happily 15wk 4days.

I have no idea what I my hcg levels were doing with my first child as we werent testing for it so who knows?

The first trimester is hard. Lots of worry and waiting. I wish you joy and a H@H long pregnancy!
