Hi Tanasha
I had this long an LP last month, was 16dpo. I knew it was definitely this long too as had been using CBFM so knew exactly when I'd Ov'd. It seemed very long for me, I'm usually 13/14 days.
When my AF came it was a little different and I'd had some unusual symptoms for a few days before it, so I'm not actually sure whether I actually conceived and had a very early loss. But I never tested so I'll never know.
What is your usual LP? x
