Hi Christina. I'm Greg, an installation specialist, 10 years awarded Windows MVP, and Volunteer Moderator, here to help you.
It seems like your new laptop has dual facing cameras, front and back. Generally there will be a setting in the Camera app to change which way camera is facing. In the Surface Pro it works this way:

Check the Camera app to see if you have that setting. If you can't find it then tell me what make and model PC you have and I'll try to find it for you.
