Morning sickness?

Okay... So last night I went to bed and I was fine. Then woke up around 4am and felt really hot and nauseous. I ended up in the bathroom throwing up. Then I felt completely fine and went back to bed. I fell asleep again and didn't feel bad. But then I woke up because I felt really cold. I added an extra blanket from the end of bed and was okay until I got really hot. Then cold. Then hot. Kept switching for a bit then I got really hot again and threw up. Then I felt a bit cold but was fine once i got in blankets and fell back asleep. I woke up... And have been totally fine since. I just thought it was some random bug. Like the 24 hour one... But only half hour... I told my partner though who insists that morning sickness is like that. Although no matter why I'm sick, he'll always bring up morning sickness. But he insists that the hot cold thing is really common... I actually am terrible at tracking my period. According to glow I was due 1 week ago. But I'm slack with updating it. So it is probably wrong. Although i do think I'm due about now. Maybe in the next week. But that's too early for morning sickness right?
