Dog stepped on uterus/tube

This is probably a dumb question but I can’t help myself... I’m 3 DPO and my large (80lb) dog stepped on the side of my uterus like right by the Fallopian tube on my left side (same side that was bloated during Ovulation). Anyways, could this harm anything that is traveling along there to the uterus? Is the zygote protected by anything? I’m sure I’m over reacting but since it hurt when he did it the only thing I can think is it messed up our chances... thanks for any insight.
