Ay anak, that kind of pain in the third trimester can be normal, pero kailangan mo talaga i-check with your OB para sigurado, lalo na kung bagong symptoms ito or if it's getting worse.
Marami sa amin mga nanay na nag-experience ng similar pains around this time, ligament stretching, baby's position, yung weight, pero hindi kami dapat mag-assume kasi every pregnancy is different. Kung intense na or may ibang symptoms (spotting, contractions na regular), go to your doctor or hospital na agad, ha?
Rest muna, try warm compress, and message your OB ASAP. You're almost there na!
