13DPO BFN Not sure when af is due, due to early ovulation.

Charley
I'm 13dpo I tested as my symptoms have been, tired all the time I'm sleeping through the day, migraines/headache, cramps, dizziness. I had a bfn this morning I'm not sure when af is due, due to early ovulation. Anyone got a bfp after a bfn at 13dpo?
