Chart question again...

Ashley • Been with my husband 12 years, but married Aug. 2015 :: we have two daughters 💗💗 :: TTC #3
This my glow BBT so far..would I go by my big dip that I ovulated or by the ovulation they put on my chart? If I go by the dip today would be 4DPO if I go by the ovulation they put, I'm only 1DPO? Confused, help :(
