when to go to the hospital

hi mommies, since I'm going into my 37 week and this is my FIRST full term pregnancy experience usually we go to the hospital when dah turun tanda, pecah air ketuban and contraction kan? okay contoh if kita dah rasa contraction kerap, should we wait turun tanda/pecah air ketuban? or another example bila kita dah turun tanda should we wait for contraction baru ke hospital? during my first pregnancy (baby preemie) turun tanda bloody show but no contraction, so time tu memang pergi terus ke hospital then dah ada bukaan 5cm masa tu baru ada contraction. 7 hours till I deliver my 31 weeks preemie. but kalini I'm not giving birth at hospital swasta, planning to deliver at hwkkkl for my second baby this time so im not so sure what to do/when to go to the hospital? ?
