I am 4 weeks pregnant. on 04/17 I went to have a sonogram done. the doctor was unable to see anything. They told me it might just be too early or that it was an ectopic pregnancy. I left thinking I was maybe just too early. well, just a little bit ago i used the restroom and a very small amount came out on the tissue. Does this mean that maybe I have an ectopic pregnancy and that I am miscarrying? I am really scared.
