I Am Going From The Brand-name Vivelle Dot Estradiol Transdermal

I am going from the brand-name Vivelle Dot estradiol transdermal patch system to a generic made by Mylan Pharmaceuticals. I am hoping to have the same results with the generic. The only difference I can see on the package is that each generic system contains 1.23 mg of estradiol vs 1.17 mg in the Vivelle Dot. Will that affect me differently? Both say they deliver 0.075 mg/day. Thanks.
