Symptoms of too much estrogen ( original question)
The symptoms listed below, as well as many others, often arise when estrogen overstimulates both the brain and body. All of these symptoms are exacerbated by stress of all kinds.
Many women in their thirties and early forties find that they experience moderate to severe symptoms of estrogen dominance as they approach perimenopause.
Decreased sex drive Irregular or otherwise abnormal menstrual periods Bloating (water retention) Breast swelling and tenderness Fibrocystic breasts Headaches (especially premenstrually) Mood swings (most often irritability and depression) Weight and/or fat gain (particularly around the abdomen and hips) Cold hands and feet (a symptom of thyroid dysfunction) Hair loss Thyroid dysfunction Sluggish metabolism Foggy thinking, memory loss Fatigue Trouble sleeping/insomnia PMS Estrogen dominance has also been linked to allergies, autoimmune disorders, breast cancer, uterine cancer, infertility, ovarian cysts, and increased blood clotting, and is also associated with acceleration of the aging process.

Over riding your own hormone production and shutting down activity with a low dose birth control may get better results if you can get your GP to agree.
I have always thought that HRT works much better once ovaries have settled and the brain has given up trying to induce them to work, just my own thoughts of cause.
