37+3 bloody show today

I went to do my normal routine today, 10mins walking on treadmill then rest then another walking. Went to the bathroom and saw I bled. I'm thinking bloody show, it's not bright red. But darker brownish shade. No painful contractions yet but I'm gonna look out for it. I don't really like spending time in the hospital if it's unnecessary. Hoping my lil one come out soon! When did you started having labor after bloody show?
