Sooo I have now worried myself into catastrophic thoughts!!! If, due to my ligation, I am having an ectopic pregnancy, will it take longer for me to get a positive hpt? How long do I wait after this spotting for af to arrive before seeking medical attention to see where embryo has implanted? My mind is wandering and I'm starting to freak out a little.....
