Help! Why is my temp not rising

Amber • 30 years old. We have one daughter, born on 2/10/14. TTC #2 since December 2014. Finally pregnant with #2 due 12/4/17!
Anyone have this before?? I had my "peak" ovulation test result in Sunday the 14th. But my temp isn't really doing anything since. Any insight? Please let me know!!!!
