Would you call?

I’m 35 w 4d and 4cm dilated. Last night around 11pm I went to the bathroom and had what looked like orange-ish mucus in my underwear. About 15 minutes later my lower back began hurting and hasn’t stopped since. It feels like my period is about to start. Would you go into L&D? I don’t want to go and be at the hospital for hours to get sent home.
