So after my last pregnancy that turned out to be an empty sack and had spotting at 6 weeks with that. This time I have been spotting on and off since I took the pregnancy test. I did have an a/s a week and a half ago. They found a sac with a baby and a heart beat of 110 measuring 6 weeks! But I'm just really nerves about all the brown and a little blood that I keep finding when I wipe. I do have one child that is 4 years old but I never had any spotting with her. Any insight for me?
