Pls answer

Ay honestly, hindi siya 100% accurate kahit kelan, sis! A few of us tried those calculators and lagi kaming off by a week or two compared sa actual ultrasound dating ng doctor, kasi ang cycle natin ay hindi always predictable, at hindi din sure kung kelan exactly ang ovulation. Better to go with what your OB says after the first trimester ultrasound, kasi yan talaga ang most reliable way to pinpoint the conception date at due date, plus makikita pa nila if may concerns with baby's development. Pero yung calculators, okay lang as a rough guide muna habang naghihintay ng appointment!
