Please help! !

I'm really confused a bout my chart. First of, my temps are always low because I have hypothyroidism. I know I ovulated and now I am 4 days late (AF was due on CD 32) and my temp is still above the coverline! It usually drops by CD 30 and remains low. To me, my chart looks biphasic.... someone told me they can see a triphasic pattern. ..???
