There is no discernable temp shift and no, there is no LP, as that is the time between ovulation and AF.
One of my cycles was annov. If you click the chart in my siggy and then go back to cycle 3, that's it. I got bored after CD 110 though and stopped temping. The temp shift at the end was artificial and brought on by Provera to induce a period. Annov. cycles can be very short though too. Just not mine.
