Pregnancy and haven’t got sick yet?

Alexia

Hello! I am 5 weeks and 4 days pregnant. I have had one before this one 9 years ago, I was throwing up getting morning, and night sickness, with this pregnancy I feel morning sick but I haven’t thrown up yet is this ok, and normal? I had a miscarriage last year so I’m worried. And again I didn’t throw up with that baby as well.
