Confused

Started cramping and had light pink blood flow beg 9dpo until yesterday. Temp dropped 12 dpo and now going up. Period due today and nothing. Never had a period five days early and 9 dpo before. Not sure if that was just a very early period or what. Temp same time daily 6:45 am. My chart has NEVER been like this. I always knew when temp dropped 13 dpo period was coming. Never a dip 12 dpo and rises afterwards
