I have been under the weather for two weeks. I've been to the doctor three times now and I'm apparently perfectly fine. Last Saturday I took a pregnancy test to see if I'm feeling sick because I could be pregnant. An extremely faint line showed up. But when at the doctors it's negative. I had to have an ultrasound done Tuesday and I saw something that looked a little weird in my uterus. I looked up pelvic ultrasounds and saw something that looked exactly like what I saw on the screen of the ultrasound, which was a pregnancy that's about 7 weeks along. But all but one test were BFN. I am so confused and upset since I'm still feeling crappy and they can't figure out what's wrong
