threatened miscarriage 2x in between 1 month

1st bleeding mase 8weeks. bleeding tp tak byk. check, doc scan ,mkn ubat, baby was fine. bleeding stop. 2nd happened semalam lg skali. bleeding on 13weeks+. but this time darah ketul2 same mcm kite period. sakit pun mcm period pain. again scan, baby ok . but still kuar darah. doc xbg ape2 ubat. but die remind klu dlm mase 1 jam kene tukar pad 2x(pad penuh) kene dtg hospital blk. Anyone yg experience mcm ni? bleeding but baby is still fine. harap2 sgt bleeding ni akan stop cepat. risau sgt ?
