Ovulation or Pregnant

Has anyone ever had morning sickness before ovulation im about 3 days from ovulation and i vommited this morning. Iv also been nausious the last 5 mornings but this is the first time iv thrown up. Iv taken 3 pregnancy test but all negative and i had a super weird cycle last month. My cycles come every 40 days but last month my AF showed up on day 28 but was super light spotting pink and brown no blood clots and only lasted 4 days. Im having super watery discharge and somewhat creamy now like im apporching ovulation. And my last ovulation test shows im getting close to ovulating.
