I don t ovulate is it possible for me to get pregnant without fertility meds?

No. . Only if you ovulate. Women with some conditions can ovulate after weight loss or correction of some other condition like a thyroid disorder.
No. If you do not ovulate at all then you need fertility treatment. But you need an evaluate to make sure you are not going into menopause, even at a young age. If you ovulate once in a while it is possible but very difficult to get pregnant on your own.
Depends. Ovulation dysfunction is usually a result of polycystic ovarian syndrome (pcos), the most common hormonal disorder in women. Pcos is often treated by fertility medication but ovulation has been successful through weight loss and surgery (ovarian drilling). Your gynecologist needs to determine the cause of your problem and treatment may not involve fertility medication.
