"i like this pill but, i rarely get any side affects. the taste is terrible to me though... its like a terrible mint flavor to me. your period blood might be brown, mine was, its just my little warning.  the first couple of times i thought it was early stages of pregnancy but that is a side effect that is important!  you blood being brown is not bad its just old blood. i usually get a day of brown stuff and then red the rest of the way through. 
my period also ends quicker thank god . pain wise i used to have terrible cramps to the point i would throw up it was so bad i had to stay home from school. during my period now i would get cramps but not as bad as before and just nausea."
