Gano kadalas ka nag papa-Ultrasound?

Hello mommies! I just entered my 16th week, finally 2nd trimester na. So far so good naman, last time nakapag pa-ultrasound ako was 13weeks ako. Wala pa akong schedule sa OB ko kelan ako babalik. Nakaka-praning lang i want to be sure if ok pa ba si baby? How many times or gano ka kadalas nag papa-ultrasound? Esp. Ngyong 2nd trimester? ok ba mag paultrasound kahit walang OB’s request? #firstmom #firstbaby #ultrasound #2ndtrimester
