Any Experiences With Tri Cyclen Lo?

I am currently taking yasmin birth control but went to my doctor to get switched because I was starting early and would have random bouts of nausea. I have been on yasmin for close to three years now. My doctor suggested tri cyclen Lo but after reading some peoples experiences with it I'm a little scared. I have heard of weight gain and near psychotic moods. I am small and (to be honest) terrified of weight gain. I also have anxiety so I would not be able to handle the mood swings. Any opinions on this bc or advice?
