Confused 😓

Luna 💕💕

So I went to the hospital around 7:30a.m and they told me that I am 2cm dilated and 75% effaced. I got sent home, and I been having like a mucus/blood like cloths and really bad back ache and cramps,( they have gotten really bad) should I go back to the hospital or should I wait and walk around?? First time mom😫😓🤤😱

Update: I was in active labor my water broke on the way to the hospital I was 7cm dilated,❤
