Loestrin 24 Fe and mcg

I am 40 years old had been on the Depo-provera shot for almost one year for endometriosis and had NO side effects other than a significant (25 lbs.) weight gain. After complaining to my doctor about the weight gain he changed my prescription to Loestrin 24 Fe and told me that within approximately six weeks I should see that weight start to drop off. Well, I've only been taking this BC pill for not even a full month and I have significant side effects, such as: severe headaches every day, break-through bleeding, insomnia, fatigue, mood swings, bloating, extremely swollen and tender breasts which have increased a full cup size in just a month and am still continuing to gain weight by the week. I would NOT recommend this pill to anyone.
