to detect and ma-ensure ang early pregnancy, consult your OB. at least one ultrasound sa 1st and 2nd trimester. I had mine nung 9 weeks si baby, then 18 weeks na yung sumunod. tapos itong 25 weeks na. iba iba depende sa situation nyo ni baby.
as soon as malaman mong buntis ka pwede na magpatransV ultrasound po
5-7 months po.
