10 weeks pregnant but feel normal?

Boo

I am currently 10 weeks and 4 days pregnant. I saw my baby and their heartbeat and 7 weeks and 2 days at the EPU and 8 weeks and 6 days privately. Everything was good in both and nothing to worry about. However I was feeling sick and I’ve thrown up twice since being pregnant but for this week I’ve been feeling so normal? Is this okay? And why could this be?
