Open Question: Don't know if my daughter had a miscarriage.....?

My daughter has only been on fertility treatments for a month. She started her period,ovulated,and conceived the 1st month. She found out she was pregnant on Mothers day. That night,she spent the evening in the ER. She was bleeding very heavy,and was told that he HCG level is only at 16,and her cervix was opened, so chances are, she was having a miscarriage. They told her to wait for 3 days,
