Birth control symptoms

I have been on Junel Fe 1/20 for about 4 months now, it’s a combination pill with iron and my mom thinks the iron is what’s making me nauseous. I still have really bad symptoms, my boobs are swollen, sore and even hot to the touch. I have nausea on and off all the time and slight cramps. Did anyone else have symptoms like this on this pill? Should I change the type of pill?
