I am now 17 days late for my af and am having mild cramping off and on for the last couple of weeks. Starting today I am also having brown discharge. I passed a nasty brown bit of goo or a clot or something. I have taken 5 hpt and all were neg. The last one was taken 14 days after my af was supposed to arrive. I can't see the dr until next Tuesday. At first I assumed I was preggo when af didn't arrive, then after all the neg tests I assumed I just ovulated late or missed ov all together. But now, with the brown discharge I'm not sure. I never have brown discharge before af, only after. With ds #1 I had implantation spotting and mild cramping. Right now, I do not feel preg at all- no vomiting, no tender breasts like last time. Has anyone ever experienced this? Any idea what could be going on? Please share your experience or possible answers! Thanks.
