Could I be pregnant

So I had flu like symptoms, dizziness, fatigue, and lower back pain at 3 days past ovulation-6dpo. It only occured in the afternoon and evenings. I had nipple pain at 3dpo but not since. I also have very dry cm. I also had an aversion to cheese and a heightened sense of smell. Yesterday and today I noticed that I had white particles in my urine. Today no sign of flu like symptoms but I do have a headache.
