A week ago I had some spotting and went to the doctor. Was told it was a temporary problem, a small part of the placenta is covering the cervix. There must have been some sort of strain or stress and it caused some very light, one-time bleeding. Yesterday I had a very small amount of pink discharge. Picked up the what to expect book and read that it was fine. Today I've had small amounts of light brown discharge throughout the day. I put a call in to the doctor and (since it was the end of the day) will receive a call back tomorrow. Came home from work, went to the bathroom and wiped away more light brown discharge. I'm not cramping, there's no red blood- is this normal/common?
