good evening lovlies! something is not adding up for me. I have been getting positive pregnancy tests since the end of november, had an ultrasound December 18th the tech doing my visit said she had thought I was about 4 weeks..well fast forward to today I had an appointment with my obgyn and on his doppler machine said he couldn't hear a heart beat (neither could i) but he also said I was early. just early. I don't go back to see my ob until February, it just doesn't make much sense to me and I'm still agitated because I haven't been given an estimated due date or anything and quite frankly I'm upset.
