Having symptoms doesn’t mean your baby will be alright as well. You should be glad that you could be one of the luckier mommies who got no pregnancy symptoms. Or maybe, your symptoms will only come in at a later stage. By then you want to take back your words and go back to days with no symptoms.
I could only advise you to relax and just stay safe and becareful in what you doing. Try to get more rest and not overwork your body since you are still in trimester 1. Avoid alcohol, raw and uncooked food.
