I am still confused!
Just saying randomly, if a baby implants at 7DPO (for example - just throwing random info out there) why does it matter if your AF is due 8 days later than someone else.
So say there's two women. Both O-ed on CD19 but one woman's AF is due around CD34 and the other CD40.
Why can't they both test on the same day? CD34? If they both had a baby implant at 7DPO? Why does the woman with the longer LP have to wait until CD40 to test?
Just found this on Birth.com.au:
Once your baby fully implants, they start to release a hormone called 'human chorionic gonadotrophin hormone' (or 'HCG') into your blood stream. The HCG level initially starts off very low, but rapidly increases (doubling every second day), so that within a few days to a week or so, the HCG level becomes high enough to be detected in your blood stream and urine. It is this increasing level of HCG that forms the basis of blood and urine pregnancy tests. This is also why pregnancy tests do not show up as being 'positive' until the woman's period would have been due (and why women do not start to feel the physical signs of pregnancy until after this time).
So if the baby implants at so many DPO, what on earth is it doing for the other number of days for the woman with the extra long LP? Once it is implanted the HCG is going into the blood stream.
