Nausea disappeared


I found out i was pregnant 4 days ago. ( im 4 weeks 2 days) I had nausea pretty bad since then but today nothing. I had a nap and woke up i felt fine. Im even eating properly again.I still have exhaustion and sore boobs and my test ( i did for peace of mind) is still dark. Is it normal for it to just stop ? Sorry for silly question.
