Sayang, at 33 weeks perut mengeras tu very common, tapi kena check dengan doctor just to be safe, okay? Bisa Braxton Hicks (practice contractions) yang memang tak sakit, cuma rasa tight dan tak selesa je, tapi doctor kena confirm kalau yang you rasa ni normal aje or ada something else. A few of my mum friends also had the same thing, and after doc checked, semua okay je. But jangan delay, do call your clinic or go in untuk peace of mind, especially if it's happening frequently or kalau ada bleeding or fluid leak. Better safe than sorry at 33 weeks!
