18 Dpo Symptoms

Before you’re bfp result, what early pregnancy symptoms did you have at 17-18 dpo?

I am confused with my symptoms. I am constant having headaches/mirgraines, they come in the afternoon for the past 4 days. On top of it nauseas, wet/creamy cm, bloated, gas, tiredness to where you need to take naps, dizzy, thirsty, hunger, cramps, pain in the right ovary, and insomnia. I took the test 10 days ago it was negative.

I normally do not get period due to pcos. I am taking provera and clomid.
