Ay, alam ko yan feeling, lalo na kapag mabigat ang baby at positioned siya dun! Marami sa amin na pregnant experienced na rin yan, sometimes it's just pressure from where baby's sitting, pero since may pain talaga, better to mention it sa OB mo next visit para ma-check lang and ma-rule out kung may UTI or ligament strain. Siguro try mo rin mag-shift ng position frequently throughout the day, or use a pregnancy pillow para mas komportable, baka mabawasan ang pressure sa area na yun.
