question: Hi. I dont really see any answers online that help and this is the first time I have had this happen. I had my menstrual cycle 13-16 of last month. Three days ago I started lightly spotting. It started out pinkish and getting darker. I dont know what would be causing this. Im 28 years old and never had it happen and there is a chance I could be pregnant.  When should I take a test?
