8 weeks - Nausea is gone

Hello mommys! How are you doing? I'm from Brazil, sorry about my English. 
I'm 8 weeks + 5 days and my nauseas are gone. I was feeling very bad since 5 weeks, nausea and vomiting all day. Now I don't feel anything. 
Should I be happy or should I be worried? I had a miscarriage recently and the baby's heart stoped and I just find out at an ultrasound, My nausea stoped also but I was bleeding a little at the time. Thank you!!!
