Hello po. Paano po kaya nangyari na magkaiba ang no. Of weeks sa ultrasound at 1st fay of last mens?

sharing my experience lang mi, ganon din saken. pangalawang ultrasound iba sa expected namin kung ilang weeks na siya. sign na pala yon na hindi nadedevelop ng maayos si baby. i had miscarriage last july ☹️ but iba-iba naman pregnancy journey natin, pwede rin late ka nag ovulate. but be sure to check with your ob 😊
