"i was taking tri-previfm, and then without my permission cvs switched me to this, claiming it was the same exact thing. well i&#039;m not so sure. since starting this i&#039;ve had a bunch of symptoms i&#039;ve never had on the other one like rapid heart rate, pins and needles headaches, and frequent infections. i never got pregnant and it regulated my periods. but other than that... this stuff is garbage. not worth it."
