I am going on lo loestrin fe birth control- will i be estrogen deprived on this birth control as if i was not on it? will i go into menopause

No: In fact for perimenopausal women who were suffering from intermittant hot flashes, I would pick a product like this for them. Before it was available I would use 20mcg pills like LoEstrin 1/20. It will keep your estrogen level stable. You will go into menopause when you exhaust the last follicle (egg) in your ovary. The average age of that is 51 years and a few months.
