Vaginal bleeding at 23 weeks

Nicole
Yesterday I went to the bathroom and I noticed there was blood in the toilet. It was red in color and the amount was more than spotting. It was similar to how it would look on the first day of my period. I have had no bleeding up to this point. I called my nurse and she said to only come in if there was enough blood to soak a pad in 15min and/or if there was associated cramping, which there wasn't. I kept checking myself throughout the night and the bleeding slowed down to spotting and then stopped altogether. I have no idea what happened. I'm waiting for a call from the doctor's office today and I'm on mini bed rest until then. Just wondering if anyone has had a similar experience.
