This question is actually regarding my friend's 17 year old daughter. She was sure that her daughter was pregnant! First of all, her daughter's AF was went from 3-5 days normal flow to 1 day spotting for 2 months in a row. She has been irritable, extremely tired, complaining about lower back pain and lower abdominal pain and bloating and dizziness. So they took her to their family doctor, he said it is possible that she could have been pregnant so they sent her for a blood test. It came out negative. (Thank God!) She has an appointment for an ultrasound on Friday to see what they can find. But could she have been pregnant and had a miscarriage? If she did, would her blood test come out negative?? I heard the HSG stays in your system for a while..

Thank you,
