Ehhh this sounds like it could be discharge yang normal during pregnancy, tapi sebab ada selaput putih macam tu better check with your doctor lah, even kalau tak bleeding atau sakit, dekat 34 weeks ni important to make sure semuanya okay. A few of my mum friends pun ada experience increased discharge towards the end of pregnancy, tapi each case different, so jangan self-diagnose je. Go see your gynae, especially kalau ada changes in colour or consistency, they can check properly and put your mind at ease!
