How did birth control effect your weight?

I am 19 and I want to go on the pill, I’m sexually active, my skin isn’t great and I would love for it clear that up. I also get terrible, heavy periods, which I’ve heard it can help.

My biggest fear at the moment is gaining weight, I am not overweight however I have a terrible self image and weight gain is the last thing I need.

What is your advice on this?

Did anyone’s weight change on birth control, and if so, how?

I would also love to hear about your birth control stories and if you think another method would suit me better...

thank you!
