Aww, first time mom energy! That fluttering feeling you're experiencing at 9 weeks is most likely just your uterus stretching, gas, or even your own heartbeat, baby's still so tiny na hindi pa siya kaya mag-flutter ng ganyan, usually around 16-20 weeks pa ang quickening. But since this is your first pregnancy and you want to be sure, I'd really suggest bringing it up sa OB mo sa next check-up para ma-ease your mind completely, kasi bawat body talaga ay different! A few of us first-time moms also felt weird sensations early on at the doc just reassured us na normal lang, so don't worry too much.
