My sister is 27 years old and has one child that is almost 4years old. She has had irregular periods her whole life. Recently she has was having some issues and went to a ob/gyn. They told her she was 3 1/2 months pregnant and that they could hear the heart beat. She was having pain in one side before she went in and told them this. When she went in for her ultra sound they found she wasn't pregnant after all and that her uterus was enlarged to the size of a 4 month fetus. They then sent her for labs and found she is diabetic and that her hormones were way off. They also told her she had alot of fluid and that the heart beat they found was hers bouncing off the fluid. Has anyone ever had this problem or one similiar they aren't telling her much and we are worried.
