Hi HJ
I did a HPT on sunday and got a BFN. and AF has arrived today .
Now I can start another month of TTC as well.
To answer your question : baby dance from the 12 till the 16 October. If you have a longer cycle than 28 days start later than the 12th.
I hope that helps.
Hope we both get BFP next month.

Cheers
Chris
