My morning sickness is disappearing at 10 weeks. Is this normal?

Liz

I began having morning sickness on week 5. I was nauseous but only threw up once. In fact, I’ve gained 7 lbs so far 🙁 My biggest symptom was extreme fatigue ... sleeping 12 hours a day! Now all of a sudden I’m no longer nauseous, have energy including at the gym! I’m only 10 weeks. Is this normal? My next appointment isn’t until the 26th so I’m nervous.
