Bleeding at 24 weeks

Ra

Today around 5:00 pm I went to the bathroom and noticed blood in my underwear and blood when I wiped. This persisted until about 7:00. I contacted the labor and delivery nurses and the said to watch it tonight and my doctor would call tomorrow. The bleeding stopped but light contractions have begun (probably Braxton Hicks.) has anyone had any experience with this?

**Update***

I went to the doctor today, and they did an ultrasound. She said my cervix is still closed, but she suspects I may have a shortened cervix. I am currently at the birthing center waiting for them to run more tests.
