I went into the emergency room on 02/11 with stomach pains. The doctors ordered a scan with contrast and an upper gi. They asked me if I was pregnant and I said I was not sure and that if I was it was very recent, since my last period was on 01/21 (which means I would have ovulated on about 02/05). After a pregnancy test, the results were negative. They did a stomach scan with contrast and an upper GI. Today, after realizing I am late, I took a home pregnancy test and its positive. I am worried about the radiation I was exposed to. My husband thinks I got pregnant after the 11th but I am not sure. Has this happened to anyone????
