"i started tri sprintec 3 months ago for my 15 year struggle with acne. i am 35 years old and haven&#039;t been able to battle acne until now.....sort of. it has cleared my acne by like 90%! it probably would of been 100% if it wouldn&#039;t make me stay on my period for 3 weeks at a time. i have always been regular with no cramps or period problems until now. i still have no cramps, but my period comes on whenever it feels like it! so annoying. i also have had tender breasts. i&#039;m already a ddd so i don&#039;t need any growing there please! other than that....i love that fact that my face is clearing up...i can deal with the other problems as long as my acne is gone!!"
