I feel broken....

This is my fourth pregnancy, resulting in one live birth in 2008.

I tested positive on my birthday. EDD was 08/18/2017. While at work I experienced some cramping and discharge. Just seconds after, I started bleeding. 😔 Went to the assessment center, and was ordered lab work and ultrasounds immediately. According to my last period date and ultrasound tech, I was 5w6ds. My sac was measuring 6w3d, but there was no fetal pole or anything. Just a sac. They try to reassure me that it was possibly too early, and rescheduled me for an ultrasound after the holidays.. but something just doesn't seem right. I feel broken. I don't even know how to explain how I'm feeling actually. I just needed to vent. Hope you ladies have a wonderful day!
