Haha, ako rin palaging curious nun! Honestly, wala tayong way to know for sure until the ultrasound, usually around 16-20 weeks when the tech can see clearly, kaya ako nag-abang ng appointment na parang Christmas! May mga signs na sinasabi ng iba like cravings, heartburn, or how you're carrying, pero totoo ba talaga? My mum friends and I always joke na 50-50 lang talaga kaya hindi kami naniniwala sa old wives' tales, hehe. The best part is the big reveal during your ultrasound, or if hindi mo gusto malaman, you can always ask the tech na i-seal it in an envelope para sa big announcement later!
