If you don't have PCOS, this can just be a normal thing that happens, and may not affect anything. Why did you get the TVU? Were you having pain? Trying to diagnose something while TTC?
The only thing that stands out is your uterus being anteverted. That means it tilts forward. Unless it's tilted really far, it doesn't mean much. If it was extreme, they probably would have mentioned that.

The endometrium thickness varies depending on where you are in your cycle.
The first thing I'd talk to your doctor about is the possibility of PCOS. You may not have it, but if you are trying to conceive, it would be good to know.
