Hi all, I wonder if anybody with more knowledge can help me?!
My understanding is that the CB pg tests with conception indicator give an approximate number of weeks since conception, in the form of 1-2wks, 2-3wks and 3+wks.
I've read that they can be unreliable but this is not my question.
I've also read that a fertilised egg doesn't start producing hcg until after implantation has occurred - which apparently takes place between 7-10dpo. SO! If you tested on, say, 18dpo using one of the aforementioned tests, then it really must only be testing hcg levels since implantation??
If this is so, then why are the CB tests called 'conception' indicators
Any wisdom appreciated!
