Really sick

Y'all,I've been having some morning sickness the past week. And now it is hitting me at night. Tonight is especially bad. My back is hurting constantly and I'm so tired. I took a test a few days ago and saw a faint line, I'm supposed to start on Halloween day (ironic lol a bloody day 😂) so a little over a week. Just wondering if night sickness is a thing and how I can make it ease up? If i even smell food I get so nauseous it isn't funny.
