question!

Brittany • Twin mom! My identical twin boys just turned 3 this June (2020) and our daughter is 1 1/2! Full time therapist and mom of 3 kids all 3 and under.
I know I'm supposed to have more or worse symptoms since my hormone levels are higher carrying twins but … I haven't thrown up one time. I'm nauseous most of the day but have not vomited yet. I know I should be counting my blessings but is this normal or something I should worry about?
