Hello, I took an at home pregnancy test yesterday, came out negative. I have been having on and off nausea for a while now, I went to the doctor to get it checked out, she said it was "viral" and it will pass. It did, but came back a little worse. I am a week late, I am having my normal cramps of lower abdominal and back, when I get my periods they come hard and they bleed a lot, this time I have this light brown color and when I stuck a tampon in, normally it bleeds all over the case, but nothing was on it. Is it possible that I am pregnant? I have no money to go see a doctor..
