sfx the month we conceived Ds2 was the month I forgot to take the cover of the predictor stick. So basically I thought I hadn't ovulated and forgot about it. Did't even bother to look for egg white.
I put that conception down to:
a - having lost weight/got mself fitter
b - no longer caring that month as I thought I hadn't ovulated
I was so convinced I hadn't ovulated I then spent the next few weeks doing all the things you ae no supposed to do while the egg imants:
trampolining
loads of excercise - running, huge long walk etc
I went for a 9 mile speed walk with my friend along the river and kept feeling dizzy and exhausted. She said "I bet you are PG". I said "nooo, nooo, noo"!
I think anxiety about the whole thing can make it less likely to happen.
My friend took 6 yrs of constant trying - she has a lovely baby daughter now, same age as DS2. Her cycles had been so irregular she had no idea when she ovulated.
If your body's cycles are regular that is a huge plus in your favour.
