Ok I have had two kids and I am sure I am pregnant but the doctor said I wasn't.  I have taken a variety of at home pregnancy test at home and everything is positive so I went to the doctor and did a urine and blood test and they said I was negative Sept 25th so I am late again this month for my period so I took three more test, three different brands and it clearly says and shows pregnant so I went to the doctor again and she said the urine test was negative so we pulled some more blood work and I am waiting results.  But I am just curious if anyone else has experienced this?  I have all the signs of pregnancy.  I scheduled an appointment for a ultra sound but they can't get me in for three weeks.  I am about tempted to go to the ER.  Because I am worried what is going on in my body.
