birth control
"I started out taking Tri Sprintec as a teenager. (16).  Never had any problems.  Had to switch to sprintec because of break through bleeding in my 20's.  I am now 37 and still take Sprintec.  I have never had any problems with it.  After taking it so long it has become a morning habit. When I don't need it anymore then I will feel old. Ha"
