Is this self weaning, does she really not want my milk anymore? :(

[fairysnuff]

Our DD is 1 and we are ttc#2
I stopped the morning feed about 2 weeks ago after AF appeared on CD40 (I expected it nearer CD30, so was gutted when it turned up 10 days late), figuring it may help my chances this month.
We are now on CD13 and for 3 nights in a row DD has thrown herself back off the left boob(it never was her favourite) and then only suked on the right but not taken any milk.
Really don't want to give up yet, feel so but I think DD has made her decision?

I heard somewhere, that your milk changes almost immediately that you concieve and that baby will know before you do because of this.
Is there any truth in this?

Or do you think it is just a phase and DD will get back to it in a few days?
She is not ill but had her jab (not MMR) just over a week ago.

Help

Anyone out there who can give me some support or stories of their onwn re: self weaning??
Feel so and worried that I may cut her off before she is ready if it is only a phase of being fussy.
