Pubic terribly pain at week 37+4

I had went to SGH earlier on due to terrible pain at my pubic bone and back bone area. The doc told they I had slight contraction but cervix is still close after the check. After the check I have a bleeding immediately and they told me is normal so I discharge and went back home and rest after few hours I woke up I realise my liner are all soak with blood so I called them up again and they say normally after the check there will be bleeding ask me monitor again. So I put a big pad and sleep again now woke up my pad is having blood again is this something I need to worry?sorry for the picture #firstbaby #advicepls #pregnancy
