Braxton Hicks tu biasanya irregular ja, boleh 5 minit, boleh setengah jam, depends on each person, mine were super random, sometimes hilang for days. Yang sebenarnya nanti regular, painful, dan semakin close together, plus ada cervical changes (doc confirm ja), so honestly best to check with your doctor or midwife sebab susah nak judge sendiri, especially if you're worried it's the real thing dah!
