Slow moving hcg, no sac

Stephanie

Based on my last period I am 5 weeks and 5 days pregnant. Today I went in for an ultrasound and bloodwork- they saw no sac but thick lining and nothing in my tubes. My HCG was only 972. One week ago exactly my HCG was 238 and three days before that was 77 when they confirmed pregnancy. Nurse Today seems to think this will result in a pregnancy loss. Has anyone dealt with this situation?
