Aww mama, nakakaaalaala yan talaga! Usually kapag ganyan, either super busy lang ang OB mo or they're just being careful not to worry you if everything looks normal so far, pero honestly, it's totally okay to ask directly next time, "Doc, okay lang ba lahat?" kasi right ka na na dapat sya mag-explain. A few of us moms experienced the same thing at nakadagdag lang ng anxiety namin, so hindi ka nag-iisa! Pero to ease your mind, I'd suggest calling your OB's clinic and asking kung may concerns sila or if everything was fine sa ultrasound, better safe than sorry, and doctors expect these follow-up questions from us mamsh.
