Aww, exciting! Pero honestly mama, sa 11 weeks pa lang, ang bubbles-like feeling na yan ay usually just gas or your digestive system doing its thing, most of us moms don't feel baby movements (quickening) until around 16-20 weeks, lalo na if first time mom ka. That said, every pregnancy is different, so kung concern ka talaga or if it changes, better check with your OB just to be sure and get peace of mind, okay?
