Hay, ganyan din experience ng kaibigan ko during pregnancy at after, parang may bulging or pressure sa lower back and pelvic area, super uncomfortable talaga! Honestly, that sensation of "may bubulwak" sa area na yan ay worth checking with your OB or doctor agad kasi it could be pelvic floor stuff, ligament pain, or something they need to assess properly, especially kung 26 months na and it's still bothering you. A few of us din nag-complain ng ganyan, pero iba-iba ang cause kaya important talaga ang checkup. Hoping you get relief soon, mamsh!
