Minimal symptoms and scared

I am stressing out. I’m pregnant for the 4th time. I had a miscarriage with my second pregnancy. With both of my girls I had extreme nausea and right now I really don’t have any nausea. I honestly don’t even feel pregnant sometimes. To be fair I’m only 5 weeks 4 days. Do you guys think this could be normal or I’m too early for symptoms? Any one with a similar experience? I am just nervous. Thanks in advance.
