Stopping my Loestrin Fe bc pill

Dami
I started taking this bc pill in 1/2015 after I had two dermoid cysts removed. I figured that has something to do with me dodging pregnancy scares for 5 years with my boyfriend so I just wanted to be extra precautious. I have one more week on the pack to go but I am discontinuing it tonight effective immediately. It has done nothing but give me horrible mood swings, significant weight gain that I can't seem to right no matter how much I eat right and exercise. I literally had to go see a counselor about relationship and emotional issues bc I thought I was going crazy. It almost took a toll on my relationship and it has given me so many self esteem issues due to my horrible weight gain. I feel so uncomfortable and unhappy in my own body. I just want to know if it's okay to stop taking it mid pack and it won't effect me negatively?
