Aww, first baby kasi yan so super exciting! Honestly 11 weeks is still quite early para sa quickening, pero if you're feeling something, it could be gas, bowel movement, or just your body adjusting, yan ang common sa mommies namin na nagsasabi ng ganyan sa early weeks. Better check with your OB just to confirm kung baby movements na talaga or something else, kasi bawat pregnancy is different naman, especially kung first time mo pa lang. Either way, congrats on your pregnancy!
