34 weeks pregnant and having some light bleeding!

Kari

Hi has anyone had any light bleeding at 34 weeks pregnant? I went to the hospital yesterday they check the baby and said everything look fine and sent me home in less then 1 hour. The blood looks brown but it's surely no spotting it's light. Today I'm again having some light brown blood again. Is this normal? Nurse could not explain why this is going on they think I had intercourse but I haven't in my whole pregnancy.
