36 weeks bleeding

Mary

I went to the ER last night because there was blood when I peed. Dr said I was having contractions but when he checked me I had no dilation. They baby’s HR was fine and everything else. So he said it was okay to go home. This morning I woke up and I have bleeding again. I’m nervous, they didn’t do an ultrasound when I was in the hospital. Did anyone experience this type of bleeding ? Or can anyone tell me what they think it is?
