Hi mama! Don't worry, you're not alone sa worry na ito, a few of us have been through the same thing at 27 weeks. Watery discharge is actually pretty normal during pregnancy, lalo na when baby moves around or changes position like what you mentioned about the breech movements, kaya that could definitely be causing the occasional leakage you're noticing. Since your last ultrasound at 24 weeks showed normal amniotic fluid levels, that's a really good sign!
That said, one quick tip to help you feel more sure: amniotic fluid usually has a slight bleachy or faint smell to it, while regular discharge is usually odourless, so if you notice a difference in smell or if it suddenly becomes a lot heavier than the teaspoon amount you're experiencing now, that's worth a quick call to your OB para ma-check lang. Better safe than sorry, especially now na papasok ka na sa third trimester. You've got this!
