Sabi nila pineapple causes contraction.. So hindi ako uminom ever nung pregnant ako. Well kung iisipin mo din talaga, that is rich in fiber, so it does help our digestion, and that might be the feeling na nag cocontract ang uterus mo bit the truth is its the digestive tract. Pero may chance din talaga na maapektuhan ang uterus sa pag cobtract ng digestive tract might as well dont drink that
