Ay, understandable na mag-alala ka, 33 weeks is pretty far along na! Honestly, konti lang abdominal discomfort and pelvic pain ay normal at ganitong stage (Braxton Hicks, round ligament pain, baby's weight), pero kung malalala siya or may ibang symptoms like bleeding or spotting, kailangan mo talaga i-check with your OB agad because it's better to be sure. A few of us moms felt similar pains pero iba-iba ang reasons so really need the doctor to assess kung ano ang dating sayo, don't hesitate to message your OB or go to the clinic, yan ang peace of mind mo para sa remaining weeks!
