Early Symptoms Disappeared

I found out a week ago that I’m now 4 weeks 3 days pregnant. I had a few symptoms in week 3 leading up to the BFP such as breast pain and nausea but now all my symptoms have disappeared. I’ve taken more tests and the pregnancy line is darker than the control line.

I had a miscarriage at 12 weeks in September and my first sign of miscarriage was disappearing symptoms. Is this normal for weeks 3-4??
