Try not to stress, symptoms will come and symptoms will go.
All I have is occasional nausea (and I mean once every couple days) and my nipples are sore and i'm tired (some days more than others)
As my doctor said everyone is different and don't stress if your not puking your brains out or being miserable. Both my mother, cousins, and aunts never had miserable symptoms and they all birthed healthy babies.
You'll be fine!
