For about a month I've been having pregnancy symptoms. It started with nausea after eating, or randomly occurring. It lasted for about a week and a half (and still occasionally.) About a week later I started getting cramps, they weren't similar to period cramps. They were just uncomfortable but I am still having them occasionally. Now I'm feeling discomfort in my ribs and middle back area, along with sharp twinges in my lower abdomen. I've also had intense cravings and frequent urination. The problem is I've taken about five home pregnancy tests, all coming back negative. And I had a blood test done almost three weeks ago, also coming back as negative. I'm not sure what else could be wrong with me? I need to know if anyone else has encountered this problem. Also, my mother informed me that she wasn't aware that she was pregnant with me until she was three months along. If that's relevant.
