During Pregnancy, In Which Month Or Trimester Will Have Morning Sickness?

I felt sick right from week 5 till now (week 11). Had very bad acid reflux and nausea especially in the morning and night. Almost every morning I’ll vomit gastric juice (greenish yellow, bitter tasting liquid) 😩 I used to love eating spicy food but now I can’t even have a mouth of it. I tried avoiding acidic, oily and spicy food, and it does help reducing the burning sensation I feel in my stomach. Occasionally I’ll drink coconut water and 100plus (non-carbonated) when I feel super dehydrated from all the vomiting.
