Morning sickness?

After 8 months of trying, my husband and I are finally pregnant! I can’t help but hear everyone talking about morning sickness. I’m getting worried that I’m not really experiencing any. I heard it is a good sign if you do get sick because it means your hormones are changing. I’ve had other symptoms, like sore breasts and fatigue, but that’s it. I go for my first ultrasound on Monday. I have PCOS so my cycle is very unregulated, so we don’t know exactly when I ovulated or conceived. I think I’m about 6-7 weeks. Any thoughts? Thank you!🙂
