Aww, I get why you're worried, pero kahit malaki ang uterus sa ultrasound hindi yan automatic na problema, maraming reasons kung bakit ganyan, from hormones to how the pregnancy is progressing, kaya talaga kelangan mo pag-usapan ito ng mabuti sa OB mo. A few of us mums nag-experience din ng similar findings pero naging normal lang ang delivery, pero ang key talaga is regular check-ups at close monitoring with your doctor para ma-ease ang mind mo and ma-ensure na healthy kayo both. Wag mag-self-diagnose muna, okay?
