"i changed over to the 10mg of this after my doctor recommended taking the brca testing which came back with a 41% mutation. i was on this pill for three months and got pregnant. i am now 3 1/2 months pregnant. i needed to go on a low estrogen birth control because i have three cases of breast cancer in my family and they all seem to be estrogen related. i don&#039;t know what happen, but the side affects were bad too and it didn&#039;t work. i would be careful on this, as i took mine like clockwork and i&#039;m not overweight."
