Mama, kailangan mo talaga magpacheckup sa doctor o mag-emergency agad if parang sobrang malabo na, blurred vision during labor can be serious, at hindi dapat i-ignore. Pero tama ka na mag-alala, at alam ko scary yan lalo na ngayon. A few of my mum friends had similar experiences, iba-iba ang reason, could be stress, dehydration, or pressure, pero kailangan mo ng medical eval talaga para ma-sure. Get checked immediately so they can guide you properly, okay?
