digital pregnancy test pronouncing me more pregnant than i can be

[stripeywoollenhat]

so i did a digital pregnancy test this afternoon and it's suggesting that i am 3+ weeks since conception, which is a week ahead of what is possible (donor insemination, all undertaken like a military campaign timing-wise): has anyone had this? it's not something i need to worry about, is it?

HcG levels vary wildly between women and even from one pregnancy to the next (I had non existant levels with dd and perfectly normal levels with the boys)

To give you an idea of the variation I copied and pasted this list from another site:

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:

Digital tests aren't 100% accurate as far as the dates go. When you had the sperm inseminated it may not have fertilised the egg for a few days after especially if you actually produced an egg a bit later. Also as your pregnancy is dated from the day you started your last period there are a whole number of reasons why the dates are slightly out.

thanks for responding - that is a pretty wide variation, SummerRain will just assume the small one is working hard to hang on, then

Twins?

I had an HcG of 218 at 4 weeks LMP - they were only looking for 50! (That was IVF though, so we knew 2 embies had gone back in and twins were a definite possibility).

Clearblue didgital overcooked me by a week.
