Uterus shape?

Bradie
So in my ultrasound picture, my uterus looks like a heart. This doctor that I have never met before (my doctor was out and I had to be seen cause I had brown/pink discharge two days ago and now some brown when I wipe) said because I'm measuring at 6w1d the baby isn't growing which is bullshit and my baby has an irregular heartbeat 119. so because the growth factor and the irregular heart beat factor she said I'm having a miscarriage. Here is a box that you need to put the babies remains in and bring it back. Her Exact words. Does anybody have some insight on this? Here are some pictures
