Eh, that's not normal lah, especially if you're getting breathless, Braxton Hicks okay lah hardening sikit tapi kalau until sesak nafas tu sebaiknya check dengan doctor, better safe kan! At 7 months every pregnancy is different, so yang anak pertama okay doesn't mean anak kedua will be the same. A few of my mum friends ada yang kena hard belly dengan shortness of breath tu dan doctor cek, so jangan tunggu lama okay, go get it checked out soon, just to be sure everything is good with you and baby
