I got a positive urine test on a first response. It was the exact same as when I first found out I was pregnant with my son. I then had two blood tests that came back negative. My doctor ordered an ultrasound that revealed there was fluid in my uterus and around my right ovary and the radiologist that interpreted the ultrasound image results recommended that I have a pregnancy blood test again and a repeat ultrasound. I am so confused as to whether I could be pregnant or not..
