Herbs and birth control? Bad or ok?

I take numerous herbs for breast growth, as my breasts range from 34c-36c-34d. I am sick of them going down and up. Anyways, I take/use Yasmin BC pill and Dong Quai, Fenugreek, Damiana, and Pureraria Mirifica pill and topical cream. I don't take all of them every single day. I read online that the reason that I am not seeing any results might be due to the herbs (estrogen enhancing/producing products) are cancelling out the estrogen from my BC, or vice versa. What is true?
