SOS! Brand change

Alright girls, so I used to take ortho tri cyclen lo and I felt perfectly fine with it but my dr changed my pill to Tri linyah And it's the first month and I've gained 5 pounds in 3 weeks. I know this is a side effect but is there any way I can lose that weight with ought stopping the pill? I'm highly sexually active so I wouldn't want to discontinue. Any help/advise is appreciated.
