Ay mama, very important question ito! Please talaga consult your OB-GYN first bago ka mag-decide about vaccine, sila ang best magsagot base sa specific situation mo at kung gaano kalayo ang pregnancy mo. Sa ultrasound naman, alam ko marami sa amin dito sa community na nag-ultrasound during pregnancy, pero if you're worried about accuracy, it's really best to ask your doctor directly, sila ang may expertise to explain kung may concerns ka. One of my mum friends actually had a second opinion from another OB kasi she wanted to be sure, and it gave her peace of mind. Normal lang mag-worry, but your doctor is the one who can really help settle your mind. Okay ka lang ba?
