Trinessa

I started taking Trinessa about four months ago. For the past month I have really noticed sudden weight gain. I also have been having cramps constantly,severe mood swings, my appetite has changed, and I can't wear my contact lens anymore because it feels like there is sand in them. I didn't make the connection until now, this is all because of Trinessa. Are there ano other birth control pills out there that would not have such crummy side effects. (Maybe ones that help you loose weight?) I'm going nuts!!!!!
