Does my chart look abnormal?

[meredithgrey]

Hi everyone,

I'm TTC #1 for past four months and AF keeps showing. I'm concerned about my BBT chart. I assume my LP is around 10 days and my usual cycle length is 24-27 days. I guess my temp rises when O, but then it reduces in 7-8 DPO and AF shows in 10-11 DPO. Is it normal or should temp stay high through out LP? I'm so worried

Can someone help me understand my temps please

Can you attach a chart? It's easier to explain with a visual.
