Encouragement needed!

This is my second pregnancy - history of miscarriage once before prior to healthy pregnancy. I’m almost 8 weeks and I haven’t really had any symptoms except constipation since 6 weeks. We saw heartbeat of 122 at 6 weeks 1 day. With my first child - I was sooo sick and nauseous and this second one - almost nothing. No sore boobs, minimal cramping, not much fatigue, just a little icky tummy and some constipation. I’m worried that these lack of symptoms are a sign that something has gone wrong even after seeing heartbeat. Any encouragement welcomed :)
