"sprintec gave me yeast infection, constant bleeding and loss of appetite, as well as sex drive. i haven&#039;t had a yeast infection in over ten years so i know it was the sprintec because i got the infection after first 2 weeks of using it. i have used ortho tri cyclen lo in the past with very little side effects. i thought would be the same as ortho. i am definitely switching back even if it costs more.
