I hope it works out for you hun. I am sure your family would understand if you did accidently fall pg though.

I am pretty sure I conceived DS1 just after AF, but I am also sure that I usually do O that early in my cycle (I have never charted but I have O symptoms usually before af is even gone, and I also think this would explain why 8 cycles of TTC were unsuccessful - I was basing it on Oing on day 14, but I think that's not true for me). So while it is certainly possible, I suspect that it is not very likely if you usually O later in your cycle.

Best of luck hun.
