Aw, 2cm na at 37 weeks plus, that's exciting! Honestly, it's hard to tell from photos kung dropped na talaga or just the angle, kaya best to confirm sa OB mo during your next check-up para sure, they can feel and measure properly. A few of my mum friends said their babies dropped weeks before labor, while some kahit the day before pa lang, so walang standard talaga! Keep monitoring if you feel heavier sa pelvic area, more pressure, or mas maraming discharge, and let your doctor know kung may changes. You're almost there, momsh, sending you all the good vibes!
