Help, touchpad is inverted

You know what's happening here, so straight to the point.

I have a Win10 Lenovo touchscreen + flexible laptop.
My laptop went upside down and then back to normal for a moment because I was putting it on my lap.

When it went back to normal my touchpad went inverted, meaning that when I try to make my pointer go left, it goes right and right goes left.

Help?
Thanks.
