Anyone experience excruciating headache 10/11 days after ovulation

So I have been having weird symptoms this cycle. On top of the really bad headache today, I have been having vivid dreams, on/off cramps, creamy discharge, nausea and altogether just not feeling well. However I have been getting BFNs on any tests I’ve taken. I know it could be too early to test but I still feel like if I was having early pregnancy symptoms the tests would show pos. Anyone else been getting these?
