Sayang, kencing berbuih boleh jadi normal lepas bersalin sbb hormones berubah dan badan lagi recover, tapi sebab ni first time you notice, better check with your gynae or doctor just to be sure, especially kalo dah a few weeks postpartum and ada symptoms lain macam sakit pinggang ke or buang air kecil susah, a few of us tried ignoring things lepas birth and harap-harap okay je, tapi peace of mind tu priceless kan. Don't worry lah, most likely hormonal adjustment je, tapi better safe than sorry with your health
