5 weeks 3 days

Is anyone 5-6 weeks and only feeling tired. I’ve literally only had tiredness and a tiny bit of heartburn. No sickness or nausea at all. With my first baby I was nauseous from week 4 - 11 weeks and he was a boy. Just feel a little panicky that I’m feeling good. I’ve been testing and they’re still dark, darker than the control line infact. Anyone feeling the same?
