So I went in Sunday foe a severe kidney infection which wasn't there, but totally felt like it. I get kidney stones and infections and usually know the symptoms right off. I also was super sick to my stomach and has some odd tenderness in my stomach. They did all sorts of test and said I just had some virus. Regardless they did a pregnancy test on my blood before going me the pain meds and ct scan and my hcg level was lea than one. I was 8 dpo at the time. I took that as a negative but the doctorlooked at me oddly and then told me to try testing again after my missed period. Like why would she say that if my hcg was less than 1?
