Much milder symptoms this time

Katten

I'm in week 8+6 of my second pregnancy and I feel way less nausea and tiredness than last time. It's nice of course, but it also makes me worry. Is everything ok? Could I have miscarried without knowing it yet? Is it because I'm still sporadically breastfeeding my 16 month old? So much waiting, wondering and worrying in pregnancy...

What are your experiences? More or less symptoms?
