My period is 7 days late. Took several home pregnancy test and they came back negative. Took a blood test and it came out negative. HCG level was 1. I am never late, if there's something I can count on is my period. They did a ultrasound exam and the doctor said my ovaries looked fine but my uterus had a very thick lining. He said I could either be pregnant or my period is about to come. I guess it's safe to say we can rule out pregnancy but I am confused about not getting my period. I have cramps that come and go, excessive discharge first it was egg white, then white & milky, now its in between and sometimes it looks slightly yellowish with a slight smell but nothing foul. My breast don't feel any different. I did have nausea for a few days in the morning & throughout the day but it went away. I also had diarrhea for a few days, now stool is soft (sorry TMI.) I do feel tired, more than usual but then again maybe I am thinking about it too much. I love to eat but I have been having loss of appetite and I also feel my mouth constantly dry. I keep going to the bathroom but every time I go I only urinate a slight bit but no pain nor itching. Has anyone ever experienced any of these things?
