Weird liquid leakage with blood

Hi mommies. im currently mid 37 weeks. and i need help. i was sleeping then tiba2 rasa mcm ada liquid keluar sikit2 but at that time ingat mimpi je so i ignore then i pelik sbb it went on for quite some time then i pegang panty i sedar dah soaked but the smell is not like urine at all. mcm acid and its quite a strong smell. then i g toilet to betul2 let all the liquid out pstu tgok kt toilet bowl color dia wrna pinkish red pstu ada white particles mcm lendir discharge. i dont feel any pain tapi it really concerning. should i go to the doctor or is it normal?
