I have had 3 negative pregnancy tests in the last week and a half but I am 7 days late for my period and last month was extremely light. I was more like spotting than anything. Now I am constantly exausted, moody, anxious, irritable and have gotten a headache almost daily for the past week, and I almost never have headaches. I even have a strange pain in my abdomen below my bellybutton. Its not like a cramp but more like that pulling feeling in you muscles when you stretch before a work out.
Do you think it sounds like I could be pregnant? could I even be 2 months pregnant since last month was so light?
