7w4d measuring small and slow hr

Jacquie

I had an ultrasound and it showed that baby is measuring 8 days behind. The HR is also only 96bpm. We are certain of dates so this really worries me. My ob seems worried as well. He even told me to prepare myself for a 50/50 miscarriage. This will be my third miscarriage this year. I just don't understand! 😩 Anyone else been through a similar situation?
