Although, the uterine fibroids grow best when there are high levels of estrogen, still, oral contraceptives rarely contribute to the growth of fibroids.
It is best to talk with your gyn for prescription of birth control pills with the lowest estrogen levels, or to consider non-hormonal contraception.
Birth control pills can be helpful in regulating the menses and decreasing the quantity of bleeding and cramps.
