Short peak

Brittaney

Has anyone else had peaks that lasted about 11-12 hours? Is it common? I had a peak last night about 8:30 pm and my temp was 93.2. This morning my temp was 97.05 and my ovulation tests were still dark but not as dark, they were starting to fade and that was at 8:13 am. Should I be worried that peak is not 24 hours or longer?
