I had periods irregularly but it had been continuous for the past 7 weeks. I had my periods on 8 /4. We had sex on 26/4. After that I didn't get my periods which I had to get on may. I had little sore boobs, dizziness, fever, headache so I thought I was pregnant. I had pregnancy test on 18/5 but was negative. I was wondering why and had an ultrasound test. That test showed a sac and my Dr. Told my follicle count was really low. She told I might be pregnant becos of the sac and had a blood restrictions confirm it. My blood test s were also negative? are there chances for me to be still pregnant?
