I went into the doctor on friday for a pap and because my period was over a month late. I have an iud so wasn't to sure hwo worried about it I should be. My doctor seem sort of worried about me being pregnant so she had me take a pregnancy test. Which had turned out negative. When we were done she said that when she did the pap she seen a small amount of blood at the end of my cervix and that she would guess that I was starting my period or would be soon, but if it didn't come that I should let her kno and we would look into the pregnancy thing more by doing an ultrasound or something. But how long do I wait until I let her kno, since I still haven't gotten my period and there is no sign of it coming. I am really worried about it all. Scared that maybe it is a tubal pregnancy. If anyone has any answers or has been in the same situation please respond.
