I took 3 home pregnancy tests and they all came up positive. When I went to the doctor yesterday he said that my urine test was negative. When he did an internal sonogram he said my uterus wall was extremely think but it was empty. In my past I had 2 miscarriages between my 2 and 3 months and one that I was almost 5 months but the baby didn?t have a heart beat. The doc took my blood to thought it was extremely strange that the doc?s urine tests came out negative and my EBT?s came check out my levels and then have to go back 48hrs to see if the levels were going up or not. #1 I out positive. #2 does anyone know what else this could be?
