Lo Loestrin Fe - my obgyn said take this pill for my ovarian cysts, has it been helpful for?

I read some reviews that said it caused bad acne weight gain multiple monthly periods and cramps. Vaginal pain and uterine cramping is the main reason the obgyn suggested it to me. I don't want to make my symptoms worse. And the negative side effects sound like they would make my acne that is present worse. Also I already feel over weight I am so confused. This birth control just doesn't sound like its for me. What do you think?
