Ay, first time mom anxieties talaga! Honestly, maraming changes na nangyayari sa 37 weeks kaya dapat talaga i-check mo ito with your OB kaagad, especially if may sakit na kasama, basta safe lang na siguro before delivery. A few of my mum friends had similar concerns near the end ng pregnancy at iba't ibang reasons pala, so better to get it confirmed by your doctor mismo para peace of mind mo, okay?
