Braxton Hicks memang biasa around 30 weeks, especially kalau perut cekang-cekang tapi tak sakit dan baby movements normal macam biasa, a few of us felt exactly like that at the same stage! Tapi since you're asking, better to monitor closely la, sebab tight feeling boleh jadi signs of something else sometimes, so kalau jadi lebih kerap or ada spotting/cramping, best to text your doctor or clinic terus rather than tunggu next appointment.
