16 weeks and 3 days pregnant today, chubby po ako 69 kilos and nasa 4'10 lang height .

Hey mama, totally normal yan sa 16 weeks pa lang, some moms show earlier, some later, especially kung may existing weight na, so don't compare yourself sa iba! The heaviness you're feeling is probably the uterus growing and ligaments stretching, which is a good sign. As for movement, usually first-time moms feel baby around 18-20 weeks or later pa, so wag mag-worry kung wala ka pang galaw, baka subtle lang or you might not recognize it yet as baby movement. But since you mentioned the heaviness and want peace of mind, best to bring it up with your OB sa next checkup para ma-confirm na lahat okay with baby and the pregnancy, that way you can relax and enjoy this phase!
