Sakit perut memang common masa pregnant, tapi kalau frequently kena cirit birit and bloating, better check with your doctor je to rule out anything like gastro or constipation, yang dua ni sering jadi problem during pregnancy. A few of my mum friends pun kena the same thing around mid-pregnancy, turned out some just needed dietary changes or probiotics, but some ada mild infections yang perlu treatment. Your doc can advise what's safe for you at 26 weeks.
