I just found out I am pregnant...my horomone level is 471 which means I am only 3-4 weeks pregnant. However, I just had a baby 4 months ago, who unfortunately died in a house fire. I have endometerosis, and for the past couple of days I have had this Black stringy discharge with some cramping on my lower left hip as some sharp lightning bolt pains in my anus. Possible Tubal Pregnancy or Miscarraige?
