Walk in to hospital

Hi. I am 39 weeks 4 days and i am thinking of getting myself checked in hospital. Last checked was 2cm dilated when 38 weeks and immediately after, doc did membrane sweep. Ive since lost my mucus plug and felt what feels like sharp shooting pain down under. (Exact feeling i felt when inwas 2cm dilated) and now i am feeling extremely bad back pain. Can i just walk in and request to be induced? This is my 4th. #advicepls
