Sayang, ini memang common la in third trimester, uterus yang membesar put pressure on everything, plus Braxton-Hicks contractions boleh start around 32w yang pastu terasa macam period cramps with lower back pain. But since these are new symptoms starting at 32w, better check with your doctor or midwife just to be safe, especially if the pain gets stronger or you notice anything else like bleeding or discharge changes. A few of us went through the same thing and doc confirm semua okay, cuma uterus preparing for labour, tapi definitely worth a quick check-in la!
