Uy, 38 weeks pa lang kaya totally normal pa yan, maraming mummies dito ang nag-past ng EDD nang one to two weeks before mag-labor, kaya hindi ka nag-iisa! Ang pag-labas ng buo usually starts between 38-42 weeks, so your body's probably just getting ready pa lang with those Braxton Hicks (yung paninigas ng tiyan mo) at lower back pain, na classic signs na approaching na. I'd definitely check in with your OB soon para ma-monitor kung lahat ay okay with baby at placenta, especially since you're past 38 weeks na, mas peace of mind lang para sa'yo at para ma-discuss ang options if labor doesn't start naturally by 41-42 weeks. Maraming suggestions online about pineapple, dates, evening primrose, pero honestly yung best bet pa rin ay rest, stay hydrated, at walk lang para mag-progress naturally, a few of us mums swear na pag relaxed ka, mas bumilis! Fingers crossed for you, you got this, mama!
