My sister in law is 9 weeks pregnant, and has been having pink to brown spotting for a week. She was seen in the ER last Sunday and HCG levels were in the 100,000s. We went to the doc, her progesterone levels were normal, and the baby looked great on U/S. HR 180, and even wiggled for us. Yesterday she passed a small amount of gray mucus that had some brown in it. Needless to say, she is freaking out. How do we set her mind at ease?
