implantation dip?! please help

woke up to a bbt dip. been having headaches on and off for two days and shooting pain in uterus every so often also over the past two days - feels like a pin prick but not crazy sore. 9dpo and usually have a 26 day cycle. anyone else have these symptoms and gotten a bfp later? never get headaches and this pain is a first.

negative test this morning and I expected it but hoping this was an implantation dip
