Ay nako, alam ko yan ang sakit talaga lalo na pag malapit na ang labor! A few of us third-time mums had the same thing, and honestly it's just one of those pregnancy surprises na di natin ma-anticipate, the weight and pressure down there talaga ang culprit. Best thing I did was wear loose, breathable underwear, elevate my legs pag nakahiga, at try cold compress (like ice pack wrapped in cloth) when it gets uncomfortable, pero para sure na safe lahat and hindi ito mag-complicate closer sa birth, mas better na i-mention mo sa OB mo, baka may specific advice para sa case mo especially na malapit ka na.
