Fluctuating symptoms at 6 weeks

Help! Two days ago I woke up feeling a rush of dizziness, fatigue, headache, just generally WEIRD. Like a huge surge in my hormones took place… I didn’t feel like me anymore 🫣

Ever since those symptoms have tapered off and they don’t feel half as strong anymore. I’m now 6 weeks and I’m worried that the reduction in symptoms is a bad sign?!

I had a scan at 5 weeks 4 days and no concerns from the hospital. However no heartbeat was detected as they said it was too early.

I had a miscarriage in July and baby stopped growing at 5/6 weeks so this is an incredibly nervous time for me.
