Mama, please see your OB right away to check on this, wag maghintay pa, okay? This needs proper ultrasound and expert assessment from your doctor kasi alam niya ang exact dates at details ng pregnancy mo. I know it's scary, pero ang doctor lang ang makakapag-guide sa inyo ng tama. A few of my mum friends went through uncertain early scans din, at ang OB nila ang nag-explain ng what's normal for their timeline. Please don't stress yourself alone, go to your checkup and ask all your questions there.
