I have heard a few different stories on when to BD.
From BD 3 days b4 O - and every day after that for 5 days.
*BD b4 going to sleep as sperm can travel better (with you laying down)
*Sperm at their best at 3.30 pm ?????
*they say BD every other day

You start counting days from when you first get AF (day 1) till the last day of your cycle (day b4 AF).

I know how you feel I was very luck to get preg last time as we only done it once that month as we had just moved into our house and the kids were not settleing in real good and DH and I were unpacking boxes and trying to do every thing else. It was a very hectic time and we just somehow did it at the right time. But we had been trying for a while (Nov - July) b4 we moved.

I have been told that the saliva tests are the best. They have a little micro scope in them.

I don't mind answering any questions as if I can help, all the better (thats why I joined the forum for - to help and support)

I hope we both are lucky this month
Cheers
Chris
