Ay, yan talagang common na sabi ng matatanda dito, hindi ka lang! Pero honestly, kung worried ka, mas better na itanong sa OB mo kasi siya lang talaga ang makakasabi kung okay for your specific pregnancy, may ilan kasing factors na kailangan tingnan like your blood pressure, placenta position, etc.
A few of us mums dito nag-try ng different positions pag may leg swelling or discomfort, and ang point talaga ay comfort at good circulation lang, so kung pakiramdam mo okay at walang pain or spotting, likely fine ka naman, pero peace of mind talaga ang importante, kaya quick check with doc is the best move!
