So I know this is going to sound stupid and weird but is it possible to be pregnant even if pee and blood test are negative??? I've done 4 pee tests and a blood test since September 2. I haven't had a period since end of July. I have so many similar symptoms of pregnancy but I know that they could be mistaken as something else as well. Is it all in my head or could I truly be pregnant and not know it?? I read one person say she had tests done blood and pee  come back negative and a week later find out she was 2 month pregnant. Just so many weird things going on with my body lately and no period for so long..... HELP!!!
