Usually I know why my body/cycle is out of whack but this year has proved me completely wrong. My period is now 15 days late and I've taken several pregnancy test over the course of that time which were negative. During the first week of that 2 week time frame I also took an ovulation test which was negative. Now for the past two days I have had positive ovulation test but still negative pregnancy test and NO period. The symptoms I have experienced: pink spotting for 2 days (when I would wipe, about 3 weeks ago), extremely sleepy and, now all I want to eat is junk food & a lot of it. Im very patient and calm so no mood swings but I have cried at everything also some back pain and light cramping. So HELP please! If anyone has any info, answers, recommendations they would be greatly appreciated.
