I had two days of spotting last week and now, at only 5 1/2 weeks I'm spotting again - both times were light brown but this time it turned a bit pinkish and was more mucous like this morning. I'm uncomfortable but I don't think I'm cramping. What should I do?

Spotting in early pregnancy is common. When accompanied with cramping it can indicate a threatened miscarriage. Please contact your doctor.
