My girlfriend is pregnant. She is 18 years old and about 5 weeks pregnant. The other day she went to the ER because she has been having symptoms of miscarriage. Chronic cramps in the pelvic area, stress on her back, white/pink discharge, and just last night she has been vomiting and having nausea. Although, the doc at the hospital did an ultrasound and determined that implantation was normal as well as her hormone levels. She told me that she regretted to tell the doc about her other symptoms...I suppose she only mentioned the cramping. But still I am confused, why are there so many signs of miscarriage?
