Alah, pineapple adalah okay je untuk makan during pregnancy, especially just a slice or two! The old wives' tale about it causing miscarriage is actually a myth, you'd need to eat a ridiculous amount (like kilos!) for the bromelain enzyme to be a concern, so don't worry la. A few of my mum friends also craved tropical fruits masa pregnant and their babies turned out perfectly fine. Just balance it with other fruits and foods, and if you're worried about anything, boleh tanya your gynae at your next checkup, tapi honestly I think you're safe to enjoy your craving!
