Bloody show & active labor ?

Jasmine

How long after you have your bloody show does active labor start? I went in today because my bloody show and was having contractions 2-4 mins apart. I was dilated to 2 cms but after consistent contractions for 2 hours and no change in cervix they sent me home 😭 still having the contractions just wondering how long I have to be in pain like this until active labor starts
