No nausea tonight :( is that bad?

RiRi , P & PJ’s Mom 💗💖💙
I'm about to be 9 weeks in 2 hours and I'm noticing I feel good. Like I have no nausea at all. Earlier today I felt like crap but not really nauseas just super tired like my body was done. But tonight I feel fine, i normally am nauseas. I seen my baby's heartbeat this past Tuesday and he/she is fine. 
Is this normal? I'm scared my symptoms keep me reassured
