Freaking out and need reassurance

Jenn

I had an appointment today at 13w1d. The Dr attempted to find baby's heart beat with a doppler twice with no success. I have a retroflexed uterus (example pictured below) and he said that may definitely be why he couldn't hear baby's heart. I'm also overweight. I'm just freaking out and now have to wait until tomorrow for an ultrasound! Anyone else have a retroflexed or retroverted uterus and had this issue?
