Been losing mucus plug all day.

Linni
Im 41 weeks today and started losing my mucus plug at 7 this morning. Been leaking and losing it all day. Started having contractions this morning also. Bad cramping and back ache. I get contractions about 2 in an hour. Should i go to hospital? Heard to go in if contractions are every 15 mins but mine are not that close together yet.
