I want to gain weight so badly

Most girls here struggle to loose weight but I’m that 1% that struggles to gain weight.

I would like your recommendations on what foods or things can I take to gain weight.

I’m currently on tri ortho cyclen and im afraid of loosing weight on it.

So right now I’m trying to gain 10 pounds in two weeks is my goal since I’ll be going on a trip where it will be hot and heat doesn’t help me gain weight.
