Aww congrats, mama! 18 weeks is perfect timing talaga for gender reveal, super clear usually sa ganyang gestation One of my mum friends did the same thing, scheduled her gender ultrasound around her OGTT kaya one trip lang to the hospital, which was smart since you're already fasting anyway (though matamis talaga ang glucose drink, haha!). Just make sure your OB knows na both appointments ang gusto mo same day so you're organized na, and enjoy the moment, it's such a special feeling seeing baby for the first time like that
