Miscarriage

Danielle
Has anyone ever had pregnancy symptoms, but all tests were negative (not even a faint line). Then received their period on time and had extremely heavy bleeding. This happened to me last month and I met with my Ob/gyn today and he said he thinks it could have been an early miscarriage and to monitor it this month before they will perform an ultrasound. 
Just wondering if this has happened to anyone else.
