Worried, short LP since miscarriage !

Sw
Hi ladies,
I am TTC since miscarriage....it has been a slow emotional journey. I have noticed my cycles are not how they used to be. I seem to have short LP.
I started my af exactly one week after ovulation :( 
I have read that LP must be 10-14days else I have LP defect !
Anyone else having similar problem since miscarriage?
