Ohhh sayang, at 32 weeks tu memang ada kemungkinan Braxton Hicks (kontraksi palsu) lah, tapi since sakit dia sampai ke belakang dan punggung dengan intensity tinggi macam tu, best jugak check with your doctor just to be sure, tidak ada salahnya dapat peace of mind kan, especially if it happens lagi. A few of my mum friends pun pernah rasa macam tu and the doctor just confirmed it's normal, tapi ada jugak yang kena monitored sebab ada other reasons, so better safe than sorry lah, don't wait for the next one, call your clinic or go for a check-up. Untuk elak, make sure you rest properly, drink lots of water (dehydration boleh trigger), and avoid standing or walking terlalu lama, relax je, badan you dah kena load berat sekarang!
