It's really good that you're paying attention to how your body reacts to different things. Since you're taking Yazmine, which is a type of birth control with more estrogen, adding herbs like fenugreek or maca that also affect hormones could sometimes cause issues. So, it makes perfect sense that you're being careful about that.

MSM and fish oil are usually fine to take and might help your skin and circulation in general, but don't expect them to make your breasts change dramatically on their own. Doing gentle massage, maybe with some oil or even without, and keeping a steady weight with a healthy diet can actually help support your breasts' natural fullness over time.
