5 years ago I had a tubal ligation after the birth of my third child. Last January I had a ruptured eptopic pregnancy that resulted in the obgyn to remove my tubes completely! The tubes were still separated/tied/ burned but somehow the sperm found the other end of the tube and egg! Now a year later I am spotting a dark brown blood! My period was 2 weeks ago and I'm 99% sure I am ovulating. Why would I be spotting? Should I be concerned?
